misc: Use a Makefile to ensure util/packet_pb2.py is up to date.
Rather than just ensuring that packet_pb2.py is available in general, use a
Makefile to ensure that it's also up to date in case packet.proto has
changed.
Also, remove a check that ensures that the protobuf module is available,
since python will complain if it needs it and can't find it.
Finally, remove a comment which talks about manually regenerating the
packet_pb2.py module, something that hasn't been necessary for a while, even
with the old version of this code.
