PARTIAL REVERT of "[packaging fix for containers] Drop usage of tmpfiles.d"

This PARTIALLY REVERTS commit 9f34c64543.

--

My assumption in the original commit was incorrect.

It's true we're creating the `/run/mariadb` directory at the RPM level.
However, the `/run` directory is tmpfs, which means it's non-persistent and gets cleaned after reboot.
The tmpfile.d configuration was making sure that after reboot, the `/run/mariadb` directory is recreated.
But after it has been dropped, at the time of reboot, the `/run/mariadb` dir is removed and not recreated, thus causing this issue.
