Colin Cross 979f9f9b18 Disable standalone relocation packer
We only support relocation packing inside lld now, remove calls to
the standalone relocation packer.  Any shared library built with
LOCAL_USE_CLANG_LLD := false will no longer have relocation packing.

This will also prevent relocation packing on prebuilt shared
libraries.

Also enables relocation packing on Darwin since lld will work on
Darwin.
