lxc: don't allow named listening IPv6 address on lxcbrX network interface

lxc-net enabled the IPv6 by default since v6.0.0[1], when named enabled on
system, the lxc-net which based on dnsmasq would fail to bind the IPv6
address on lxcbrX interface, that cause lxc cannot work correctly.

LXC upstream changed the default v6 address again[2], we need to line up with
upstream. Updated the lxc-net default v6 address to named.conf.option to tell
named don't bind and listen that address.
