cubicweb #1216365 Listen only on localhost when host=localhost [validation pending]

The cubicweb daemon should only listen on the 127.0.0.1 when host is defined to localhost (and not the machine name).

Right now we get

# netstat -apn| grep 8080
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      21343/python

I was expecting

# netstat -apn| grep 8080
tcp        0      127.0.0.1:8080            127.0.0.1:*               LISTEN      21343/python
