[MINOR] unix sockets : inherits the backlog size from the listener 

Since unix sockets are supported for bind, the default backlog size was not
enough to accept the traffic. The size is now inherited from the listener
to behave like the tcp listeners.

This also affects the "stats socket" backlog, which is now determined by
"stats maxconn".
