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 https://gitlab.gnome.org/GNOME/gobject-introspection/blob/1.60.1/NEWS
