Fix `BKE_library_make_local()` trying to also make local proxified objects.

Proxified objects can never be local, we can totally ignore them here.

This 'fixes' the asserts related to usercount when trying to remap poselib
of localized proxified objects (not sure what exactly was going on wrong here,
but proxies are a giant can of worms for sane data-blocks handling anyway :/).
