fix: restore native arch binary after packaging and skip testpackage for cross arch

The previous fix left the x86_64 binary in lib/binding/ after packaging,
causing tests to fail on arm64 CI runners. Now we package the cross arch
first (without testpackage since it can't be loaded), then the native
arch last (with testpackage) so the correct binary remains for tests.
