refactor(nix-compat/store_path): take [u8;32] for outer fingerprint r/7691
The outer fingerprint used for store path calculation is always a sha256
digest. This includes both input and output-addressed store paths.

We used a NixHash here, which can also represent other hash types, and
that had a bunch of annoyances:

 - Whenever we had the bytes, we had to wrap them in a NixHash::Sha256().
 - Things like AtermWriteable had to be implemented on NixHash,
   even though we then had an assertion it was only called in the
   NixHash::Sha256 case.
