tests/slapgrid: make test more deterministic

`test_one_failing_daemon_in_service_will_bang_with_watchdog` often fail with:

```

```

This test uses a service that will create files `launched` and `crashed` files
when running, and just after telling supervisor to start the service test
inspects the directory content.
If service had time to start, then files are created, otherwise they are not.

Change the service to wait for a delay before creating the files to reduce the
change of race condition here.
