test: rename `dracut_install` to `image_install` The `dracut_install` is a misnomer, since the systemd integration test suite is based on the original dracut's test suite, and not all the references to dracut has been edited out.

core: ensure init.scope is realized after drop-ins have been loaded If we add a drop-in for init.scope (e.g.: to set some memory limit), it will be loaded long after the cgroup has already been realized. Do it again when creating the special unit. 2023-01-20 23:00:38 +00:00			`EOF`
