Subject: [PATCH] voipchat: don't simulate DNS failure.

It only causes the program to fail to start, as it's the only DNS lookup,
so it becomes a pain to get the example running at all at high packet-loss
rates, when what you _really_ want to see here is what it sounds like when
packets go missing.
