pcap-client: Don't bind to second 'traffic' udp port 

if the tester runs on a different host/IP than the IUT (like in our
dockerized jenkins tests), then of course we cannot assume that
traffic sent by the tester can be received by the tester again.

So rather than binding/connecting two sockets, let's only use one
and send packets without caring if there is a remote receiver.
