revert to 'suseInsertService chronyd' #54

[phillxnet]

Update our chronyd config via Kiwi-ng build-in. This brings us closer to our JeOS Leap 15.3 Appliance upstream. Dropping our prior my-hand additional server configs.

Fixes #54

After this change we have:

And we have our expected provider of the above config:
