protobuf: update to 3.11.2
This PR updates the protobuf package and subpackages to version 3.11.2. Google updates the major version of its shared libraries with every release, and this moves libproto*.so.18 to libproto*.so.22. Accordingly, this PR also:

* Revbumps all packages dependent on these shlibs
* Renames the libproto{c,buf,buf-lite}18 subpackages to drop the major version from the name
* Adds "replaces" directives to these subpackages to record the name change.
