            Use protobuf in version 3.x only

This is part of https://fedoraproject.org/wiki/Changes/Protobuf_5.x/6.x
This package does not sucessfully build with new protobuf per
  https://copr.fedorainfracloud.org/coprs/mochaa/protobuf/monitor/
so limiting to protobuf version 3.
Once the protobuf is rebase this will automatically pick up compat
package protobuf3

I am not bumping release as this does not need a rebuild now.
