Vladislav Grishenko b0cd672abf ssdp: fix M-SEARCH replies on non-linux OS and drop broadcast receiving due no read ...

On Darwin & *BSD binding to mcast address may force NITIFY packet send from
 this mcast address, not from primary interface address. Therefore subsequent
 NOTIFY packets might be ignored by some clients, including Samsung Smart TV
 and they will stop & disconnect after initial max-age timeout.

 SO_BROADCAST on notify packets is not needed, because there's no broadcasted
 M-SEARCH packets and notify socket queue is never read.
