server/camnetdns: make it work
server/camnetdns: make it work

Before that change, one would only get a response to a DNS query, if
directly sending the query to the dns server.

I think the main problem was that one has to copy the question section
of the query in the response message, which is part of what SetReply
does.

With this change, I seem to get responses (for e.g. www.camlistore.net
and 6401800c.camlistore.net), without having to specify a server to
query to dig (or nslookup), so by letting the resolver and the DNS
hierarchy follow its normal course.

Issue #722
