fix: restart service after config change (#36)

* fix: restart service after config change

When chrony was already installed, the service currently does not get
restarted when the config file is changed. I added a "watch" option to
the service.running state to ensure it gets a restart when we adapt the
configuration.

* fix: replace require completely with watch to ensure service restart
