Update MariaDB version to 10.6.7

We also modify workaround applied for 10.6 upgrade wrt to bug [1]
as it has been added extra tools to help with checking state of upgrade.

New flag --check-if-upgrade-is-needed is checking if any upgrade is
already running and waits until it's finished.
It exits with rc 0 if upgrade is required and 1 if not.

If upgrade is required, we fall into rescue and perform upgrade.
