systemd: Default to non-stateless images

Browse Source 
When creating images, for anything other than the explicitly stateless
case, touch /etc/machine-id so that the images can be booted without an
initramfs and with `ro` set on the kernel command line, otherwise system
refuses to start:

  [    7.222134] systemd[1]: No hostname configured.
  [    7.227266] systemd[1]: Set hostname to <localhost>.
  [    7.232622] systemd[1]: System cannot boot: Missing /etc/machine-id and /etc is mounted read-only.
  [    7.241750] systemd[1]: Booting up is supported only when:
  [    7.247362] systemd[1]: 1) /etc/machine-id exists and is populated.
  [    7.253752] systemd[1]: 2) /etc/machine-id exists and is empty.
  [    7.259757] systemd[1]: 3) /etc/machine-id is missing and /etc is writable.

If IMAGE_FEATURES includes `stateless-rootfs` then systemctl-native is
not run on the image leaving the image for population at runtime by
systemd.
