This commit add a wrapper for procd services, to add a callback script
if the "service.restart" trigger event was fired.

Example:

service_trigger() {
	procd_add_trigger
	procd_add service_trigger "service.restart" "firewall" <script>
	procd_close_trigger
}

If the firewall was restart, then the stored script gets executed.
