Subject: [PATCH 2/3] python3Packages.protobuf: check version compatibility

Let's avoid situations from #459656 early, e.g. log
https://hydra.nixos.org/build/312538974/nixlog/1/tail

Note that python3Packages.protobuf is in protobuf.tests,
so that we should notice when updating protobuf in particular.
