refactor(tvix/derivation): pass fingerprint to build_store_path r/5738

All of these occurences are actually sha256 digests of some fingerprint
- which means there's not a lot of need to do the hashing outside.
Instead of passing in a digest, keep the sha256 hasher in the function,
and pass in a fingerprint.

This makes it much easier to construct fingerprints using format!() in
all consumers, because we need don't need to juggle with the hasher
anymore.
