* Ease switching from galera-3 to galera-4 on upgrades from buster
The underlying bug is a Conflicts cycle in galera-[34] that causes default-mysql-server/mariadb-server-* to be removed instead of being upgraded on various upgrade scenarios. No dataloss happens, just a surprising upgrade outcome. The complete fix requires an update of galera-4, too.
