zdtm: socket_udp_shutdown: Make the test fail instead of timing out.

Browse source 
When -- after restore -- sockets can't communicate, the test times out
while waiting on recvfrom(). Since the communication is local, send()
works instantaneously - so mark sockets with SOCK_NONBLOCK and report
failure if the message is not received immediately.
