vlib: stop worker threads on main loop exit
If not, worker threads may continue own loops after deinit and/or thread0 exit with related crashes due no rpc capability, unmapped shared memory, etc. Main loop exit handlers that uses barrier sync will be happy too as long as recursive barrier sync is supported.
