setBroadcast(true) not working on Android

[Rapsssito]

When calling socket.setBroadcast(true) on Android after binding the socket, it makes whole the process hang forever. This method works on iOS.

I think it is related to the Android part. It looks like the process hangs on setting the socket broadcast to true.

There could be useful info in #82 and @shynst's commit in his fork: shynst@aef3f01.

I'm indeed seeing the hanging behaviour here. It even results in an error in a flow where you:

1. create a udpv4 socket
2. bind it
3. set broadcasting
4. call socket.close

That will throw an error Socket is closed from inside the setBroadcast method because it is still hanging.

Anyway, I've found that I can just omit the call to setBroadcast completely for Android. It nog longer produces the error or hangs the call (duh), but is still able to use UDP broadcasting just fine without it (Android 8, 9 and 10)

Duplicate of #82, moving discussion over that issue.
