Sending multicasts out of Sockets without setting the broadcast to true - causes the error "Bad value for ai_flags" on some systems (#3404)

Browse Source 
The underlying cause looks to be https://github.com/dotnet/runtime/issues/28630.

Basically, it's an access denied bug.
It looks like multicasts need the same access rights as broadcasts on some systems.
