lxc: Make named avoid listening on lxc network interface

lxc-net wants to take care of DNS itself using dnsmasq, while named in
bind does the same thing on all network interfaces by default and causes
the following error.

dnsmasq: failed to create listening socket for 10.0.3.1: Address already in use
Failed to setup lxc-net.
