refactor(nix-compat/store_path): drop build_nar_based_store_path r/8822

This is the only (remaining) occurence of it, and not really
more code than just calling store_path::build_ca_path with
`CAHash::Nar(NixHash::Sha256(…))`, especially considering we need the
CAHash in the PathInfo struct later anyways - so let's remove this
function.
