lib: ostream-multiplex - set ostream_private.parent

Unlike with istream-multiplex, there are no issues with I/Os. Only the
parent stream will have the I/O. Using the default parent adds the
missing methods that otherwise would have needed to be implemented:
 - cork
 - flush_pending
 - switch_ioloop
