[PATCH 10/16] conf: Correct setting of dns_match address in add_dns6()

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.
