Joachim Wiberg c5015faafe dnsmasq: only listen on loopback :53, as local resolver
Even though dnsmasq only listened to requests from 127.0.0.1, port 53
was visible using nmap.  We only use dnsmasq as a local resolver, so
we can safely change the config to bind to loopback instead, and at
the same time get less noise from nmap scans.

# dnsmasq is the system resolver, the file /etc/resolv.conf is
