TT#36284 Move back mariadb.service from Wants to Restores for proxy

The kamailio-proxy daemon really requires a mariadb instance running,
otherwise it will fail to even start. It might be able to manage a
mariadb instance disappearing for a short period of time during normal
operation depending on the options given.

Fixes: commit 27c63cdf14
