Remove the NNG_OPT_IPC_SECURITY_DESCRIPTOR option.

This is now replaced with nng_listener_set_security_descriptor
and nng_stream_listener_set_security_descriptor functions.  We
may elect to remove these entirely, but for named pipe users they
are probably still quite useful.  Moving towards UNIX domain sockets
would obsolete this functionality.
