Move the handling of the list of enabled and disabled systemd services
more to the end of the `os` pipeline, just before the SELinux stage.
This has no functional effect on produced images, but it will make it
nicer once the handling of the custom files and directories will be
added to the pipeline. Specifically it should be added right before the
services stage to allow enabling custom service files, but after all
other configurations that are applied to the image.
Regenerate all manifests.
