fix slirp4netns resolv.conf ip with a userns

Browse Source 
When a userns is set we setup the network after the bind mounts, at the
point where resolv.conf is generated we do not yet know the subnet.
Just like the other dns servers for bridge networks we need to add the
ip later in completeNetworkSetup()
