Julian Stecklina 5de0b3e54a stub: rename sections for UKI compatibility
systemd 255 is stricter in what it considers UKIs. It demands .linux
and .initrd sections. Rename our sections that contain the respective
filenames to match these names.

Julian Stecklina ec05d707f3 tool: always include version in PRETTY_NAME
... to give a consistent user experience in systemd-boot.

Fixes #220.

tool: make stubs input-addressed
The stubs on the ESP are now input-addressed, where the inputs are the
system toplevel and the public key used for signature. This way, it is
guaranteed that any stub at a given path will boot the desired system,
even in the presence of one of the two edge-cases where it was not
previously guaranteed:
* The latest generation was deleted at one point, and its generation
  number was reused by a different system configuration. This is
  detected because the toplevel will change.
* The secure boot signing key was rotated, so old stubs would not boot
  at all any more. This is detected because the public key will change.

Avoiding these two cases will allow to skip reinstallation of stubs that
are already in place at the correct path.

tool: make kernels and initrds content-addressed
Kernels and initrds on the ESP are now content-addressed. By definition,
it is impossible for two different kernels or initrds to ever end up at
the same place, even in the presence of changing initrd secrets or other
unreproducibility.

The basic advantage of this is that installing the kernel or initrd for
a generation can never break another generation. In turn, this enables
the following two improvements:
* All generations can be installed independently. In particular, the
  installation can be performed in one pass, one generation at a time.
  As a result, the code is significantly simplified, and memory usage
  (due to the temporary files) does not grow with the number of
  generations any more.
* Generations that already have their files in place on the ESP do not
  need to be reinstalled. This will be taken advantage of in a
  subsequent commit.

Raito Bezarius 0107754d62 tool(architecture): make it generic
Architecture is now a generic structure that can be specialized
via an "external" trait for generating the paths you care about
depending on your target bootloader.

Raito Bezarius 609c11f26d tool(systemd-boot): install it once instead of checking for each generation
systemd-boot is now installed once for many generations rather than multiple times.

This means it is not really possible to manage different system in the same "machine", which is a very
obscure usecase, theoretically possible, but not yet encountered.

Raito Bezarius e5c1d74e3f tool: introduce --target-system to choose target architecture
We will hard fail in case of encountering different architectures in bootspec.
This should still be compatible with cross-compiling systems in the future.
