Add the galera_client dependency to the repo build

This change is required because without it the client libraries
used to build the MySQL-Python packages will depend on the base
system and they will be wrong.

This is an example of the issue:
  http://paste.openstack.org/show/492788/

This will cause multi node production issues when building a
standalong repository outside of the the OpenStack gate.
