In the subimages we also want to make sure all dependencies of the systemd packages are cached so reuse the same prepare scripts from the main image to do that. We only want required dependencies in the subimages, not recommended or suggested dependendencies, so add an environment variable $SYSTEMD_REQUIRED_DEPS_ONLY which the prepare scripts can check for and enable it for the subimages.
