Now that ICMP pass-through from socket-to-tap is in place, it is easy to support UDP based traceroute functionality in direction tap-to-socket.

We fix that in this commit.

Applied! (and tested quite a bit, with "long" and "short" traceroutes). By the way, it occurred to me that supporting ICMP probes (try with 'traceroute -I') might also make sense, eventually, if it's simple enough (I *think* it is, we could probably set the TTL on the socket regardless of the transport protocol). -- Stefano
