protobuf changed it versioning scheme [1]. The Release version is now only the
Minor.Patch version of the language specific version.
C++ stays on Major version 3, but python got bumped to 4. So the handling in
the .mk files changed to reflect that.
python-protobuf changed it version to 4 because of some breaking changes,
see[1].
