tests: Reduce usage of timeout_add() and sleep()

* Instead of waiting for a fixed time, use a timeout and stop the main
  loop right after the test has succeeded.
* Replace time.sleep to sync processes with os.pipe communication
* Chain idle sources instead of using multiple timeout sources
* Replace sleeps with unbufferd communication
