vpnmain.cgi: Allow to use PSK if public IP is '%defaultroute'.

Openswan did not support to use PSKs on net-to-net connections,
when the public IP of the IPFire box was "%defaultroute".
However, it is required to set the public IP to "%defaultroute"
on NAT-ed devices (such as UMTS connections in Germany) to
connect to other sites as the IPFire box does not know
the real public IP address.
