[PATCH] tests/qtest/netdev-socket: Do not test multicast on Darwin

[Philippe Mathieu-Daudé]

Do not run this test on Darwin, otherwise we get:

  qemu-system-arm: -netdev 
dgram,id=st0,remote.type=inet,remote.host=230.0.0.1,remote.port=1234: can't add 
socket to multicast group 230.0.0.1: Can't assign requested address
  Broken pipe
  ../../tests/qtest/libqtest.c:191: kill_qemu() tried to terminate QEMU process 
but encountered exit status 1 (expected 0)
  Abort trap: 6
