Attempt to fix macOS-on-silicon wheel building

The wheel produced for arm64 macs is b0rken, as if the shared object was
not properly linked against the static libpg_query.a library.

Try out suggestion found in
https://stackoverflow.com/questions/4597228/how-to-statically-link-a-library-when-compiling-a-python-module-extension,
where the static library if specified in extra_objects instead of a
normal library.
