description:
Disabled cloning of sockets without master process (ticket #2403).

Cloning of listening sockets for each worker process does not make sense
when working without master process, and causes some of the connections
not to be accepted if worker_processes is set to more than one and there
are listening sockets configured with the reuseport flag.  Fix is to
disable cloning when master process is disabled.
