ba74b1fea1 doc: Extend zero-recv test with methods using msghdr
This test program verifies that we can receive and discard datagrams by
using recv() with a NULL buffer and zero-length.  Extend it to verify it
also works using recvmsg() and either an iov with a zero-length NULL
buffer or an iov that itself is NULL and zero-length.

socket without needing a big discard buffer, by using a zero length recv().
