Add fips-3678 feature (#52)
* Add rerun-if-env-changed instructions for BORING_* variables

* Use X509_get0_notBefore() and X509_get0_notAfter() instead of X509_getm_notBefore() and X509_getm_notAfter().

According to
https://www.openssl.org/docs/man1.1.0/man3/X509_getm_notBefore.html,
"X509_getm_notBefore() and X509_getm_notAfter() are similar to
X509_get0_notBefore() and X509_get0_notAfter() except they return
non-constant mutable references to the associated date field of the
certificate".

* Only update boringssl submodule if BORING_BSSL_PATH not provided

* Allow BORING_BSSL_LIB_PATH to control link search

* Add fips feature

* Use X509_set_notAfter unconditionally for FIPS compatibility

This is equivalent according to
https://boringssl.googlesource.com/boringssl/+/c947efabcbc38dcf93e8ad0e6a76206cf0ec8072

The version of boringssl that's FIPS-certified doesn't have `X509_set1_notAfter`.
The only difference between that and `X509_set_notAfter` is whether they're const-correct,
which doesn't seem worth having two different code-paths.

* Check out fips commit automatically

* Verify the version of the compiler used for building boringssl

NIST specifies that it needs to be 7.0.1; I originally tried building with clang 10 and it failed.
Theoretically this should check the versions of Go and Ninja too, but they haven't given me trouble in practice.

Example error:
```
   Compiling boring-sys v1.1.1 (/home/jnelson/work/boring/boring-sys)

* Add Github actions workflow testing FIPS
