Updated the shlib patches:
- Upstream now forces basename in sanitize_shlib_path(lib) if the system isn't
darwin. We patch the function to always prefer absolute paths
- Due to the above we no longer need the macos patch
- `sanitize_shlib_path` is applied after `resolve_from_ldd_output` so we need to
apply `fallback_libpath` afterwards too (else we get stuff like
`/nix/store/...@rpath/foo.dylib` on darwin)
- Note that the `fallback_path` no longer have any unit tests
