MDEV-33727 mariadb-dump trusts the server and does not validate the data

Browse Source 
safety first - tell mariadb client not to execute dangerous
cli commands, they cannot be present in the dump anyway.

wrapping the command in /*!999999 ..... */ guarantees that
if a non-mariadb-cli client loads the dump and sends it to the
server - the server will ignore the command it doesn't understand
