Update MariaDB client version to match server
Update MariaDB client version to match server

The server and client versions are currently mismatched, resulting
in a failure for the 'metal' jobs where the client is installed
by the utility playbook, before the galera-server playbook.

This patch ensures that the version for the client is set to the
same as that in galera_server.
