checkInputs used to be added to nativeBuildInputs. Now we have
nativeCheckInputs to do that instead. Doing this treewide change allows
to keep hashes identical to before the introduction of
nativeCheckInputs.
Mopidy-Local is the successor to Mopidy-Local-SQLite and
Mopidy-Local-Images, which are already packaged. I had to make
gobject-introspection a propagated build input, otherwise
Mopidy-Local can't import Mopidy.
