[Net] ENet non-relaying server now process broadcasts.

Setting `server_relay = false` prevents the server from letting clients
communicate with each other, but without this fix, the server would also
ignore broadcast packets.
With this change, the server still does not relay messages to other
clients, but will correctly process broadcast messages (and "exclusive"
messages) as if they were directed to just the server.
