atomic-vagrant: Mask cloud-init instead of using rm on /etc

Now that cloud-init is enabled in the systemd unit, that change
goes in /usr/lib...which we can't easily change.  There are
two potentially sane solutions:
 - Refactor the kickstarts here
 - Some support for systemd presets in kickstart files would
   allow us to have a later override here
