MDEV-30275: mariadb names rather than mysql names should be used

* mariadb-service-convert to use mariadbd-safe
* galera_recovery to use mariadbd
* mtr - wsrep use mariadb executables
* debian/mariadb-server.mariadb.init use mariadbd-safe
* debian/tests/smoke uses mariadb instead of mysql as client.
