TEST-13-NSPAWN: several cleanups

- suppress unnecessary error messages, especially in loop and at_exit(),
- ensure the container service is stopped before restarting,
- do not send KILL signal, as garbages will remain, and disturb the next
  invocation,
- drop unnecessary workaround of trying machine twice.
