Make libprotobuf symbols local on OSX (#8346)

@gnossen gave a great overview in https://github.com/grpc/grpc/pull/24992 of the overall problem.

If a python process using both protobuf _and_ another native library linking in libprotobuf
frequently can cause crashes.  This seems to frequently affect tensorflow as well:

tensorflow/tensorflow#8394,
tensorflow/tensorflow#9525 (comment)
tensorflow/tensorflow#24976,
tensorflow/tensorflow#35573,
https://github.com/tensorflow/tensorflow/blob/v2.0.0/tensorflow/contrib/makefile/rename_protobuf.sh,
tensorflow/tensorflow#16104

Testing locally this fixes both crashes when linking in multiple versions of protobuf
and fixes `DescriptorPool` clashes as well (e.g. Python and Native code import different versions of the same message).
