Raito Bezarius 4ef6957f88 feat: enable synthesis support
Bootspec has a mechanism called synthesis where you can synthesize
bootspecs if they are not present based on the generation link only.

This is useful for "vanilla bootspec" which does not contain any
extensions, as this is what we do right now.

If we need extensions, we can also implement our synthesis mechanism on
the top of it.

Enabling synthesis gives us the superpower to support non-bootspec
users. :-)

Disable GC if there are any malformed gens to avoid catastrophic failure

tool: Use mtime of the symlink rather than the target
When using the target, this will always result in a timestamp from 1970
because the symlink points to the store.

nikstur 8efc061e1d tool: add comment for log level of malformed gens
The message about malformed generatiosn should semantically be a
warning. However, since users might have hundres of old and thus
malformed generations and can do little about it, this should remain a
debug message. This way the user is not spammed with no-op warnings
while still enabling debugging.

Julian Stecklina be458e3385 tool: avoid creating unbootable system
lzbt currently happily nukes all boot entries, if it can't parse any
bootspecs. With the upcoming incompatible bootspec change, this might
be a problem that's worth avoiding. :)

I changed lzbt to fail hard in case, it can't generate any boot
items.

Julian Stecklina cbccd64c57 tool: make file installation deterministic
Due to the use of hash maps, the order of file installation was not
deterministic. I've changed the code the use BTreeMaps instead, which
makes this deterministic. While I was here, I tried to simplify the
code a bit.

nikstur 75a19cd818 tool: correctly sort generation links
To correctly overwrite existing initrd with newer secrets (from newer

nikstur 362205c2ec tool: check file hashes before copying
To minimize writes to the ESP but still find necessary changes, compare
the hashes of the files on the ESP with the "expected" hashes. Only copy
and overwrite already existing files if the hashes don't match. This
ensures a working-as-expected state on the ESP as opposed to previously
where already existing files were just ignored.

nikstur 3a3ad7c40d tool: write all generation artifacts at once
Previously, generations were installed one after another. Now all
artifacts (kernels, initrd etc.) are first collected and then installed.
This way the writes to the ESP are reduced as duplicate paths are
already removed in the collection phase.

nikstur df6b1b07f7 tool: use random names for secure tempfiles
Using random names for tempfiles makes handling them easier. It reduces
the amount of noise in the code because no custom name needs to be
provided for each tempfile. The names were not really useful in any
case.

It also does not burden the developer with ensuring uniqueness of names.
This is relevant when files for multiple generations need to be stored
in the same directory (e.g. because they need to be accessed after
handling one generation).

Out of an abundance of caution, 32 random alphanumeric characters are
chosen for each filename. The tempfile crate, in comparison, only
chooses 8. 32 characters should be enough to avoid collisions, even
if the PRNG is not of cryptographic quality.

nikstur a8d9ea128d tool: improve sd-boot generation display name
Leverage the bootspec `label` field in its intended way. The VERSION_ID
of the os-release in the stub now only contains the generation number
and the build time. This makes a correct PRETTY_NAME entirely dependent
on correct information in the bootspec `label` field.

nikstur 06f921ead0 tool: read build time from symlink
Read the build time from generation symlinks in /nix/var/nix/profiles
instead of from the underlying derivation. The derivation build time
will always be a UNIX epoch of 0 because of the `nix-build` sandbox,
which is useless for identifying when a generation was created.

Do not sign the kernel
Malicious boot loader specification entries could be used to make a
signed kernel load arbitrary unprotected initrds. Since we do not want
this, do not sign the kernel. This way, the only things allowed to boot
are our UKI stubs, which do verify the initrd.

nikstur ce3b2c27b5 tool: write systemd-boot loader.conf
To minimize the number of arguments passed to `lzbt`, the loader config
is assembled outside `lzbt` and passed as a single argument.

Instead of reimplementing `consoleMode` under the `lanzaboote`
namespace, `config.loader.systemd-boot.consoleMode` is reused as is.
