lxc-php: Make mysql socket binding work on fresh install

/var/run/mysqld only exist after mysql is installed, as such the role
lxc-php need to run after the role mysql.

Also only cause a restart of the containers when their configuration has
been changed.

For now socket binding might only work for mysql and not mysql-oracle
(it's default socket seems to be /tmp/mysql.sock).
