1. The tests/test_radio_dish test implements is_multicast_available() to …

   verify that multicast is working on the system before running tests
   that relies on this, or skipping those test otherwise.
   
   In some circumstances this check itself hangs due to the recvfrom()
   call being blocking waiting for data. The test is eventually killed
   with a SIGALARM signal.

   With this commit, making the recvfrom() call non-blocking. The test
   does noy hang, and the non-available multicast is detected and the
   tests needing it are skipped:
