systemd-container: recommends StartExecPre modules

The systemd-nspawn@.service file uses the following line to try
loading the tun, loop and dm-mod kernel modules, in a non fatal way:

    ExecStartPre=-/sbin/modprobe -abq tun loop dm-mod

A non-zero return code from modprobe will not stop the service from
starting, but it would be convenient to inform the user about this
optional support, so add these modules to RRECOMMENDS.
