Most tests for TCP sockmap can be adapted to UDP sockmap if the
listen call is skipped. Rename listen_loopback, etc. to socket_loopback
and skip listen() for SOCK_DGRAM.

FWIW, Go has net.ListenUDP so I don't think it would be very confusing
to leave the helper name as is.

Expand the TCP sockmap test suite to also check UDP sockets.
