chore(ci): Remove unnecessary commands from new CI setup

* remove a step that was not supposed to be committed ("Do we have
  Docker?")
* remove setup of old temporary storage directory (now done in
  integration script test instead)
* skip creation of out-link for initial Nixery build (to avoid
  cache-busting on the second build)
