In golang/go#37319, TestPacketConnReadWriteMulticastUDP was observed to occasionally fail with ENOBUFS on macOS. This change adds a retry loop for that test function. There are some other related test functions that may also wrap sendmsg, but I have not observed any ENOBUFS failures for them — I suspect that some difference in protocol or traffic class prevents this failure mode, but we can always add more retry loops if we discover that they are actually needed. Fixes golang/go#37319.
