add_dns6() (but not add_dns4()) has a bug setting dns_match: it sets it to
the given address, rather than the gateway address. This is doubly wrong:
- We've just established the given address is a host loopback address
the guest can't access
- We've just set ip6.dns[] to tell the guest to use the gateway address,
so it won't use the dns_match address we're setting
Correct this to use the gateway address, like IPv4.
