examples: add a superfluous rm -rf line

I often disable the `rm -rf tmp` line to make iterating quicker (by
removing the need to pull and write previous layers and objects) but in
order for that to work you still need to delete a couple of things.  Add
a second line so that you can comment out the first one while you're
working, like:

  # rm -rf tmp
  rm -rf tmp/efi tmp/sysroot/composefs/images
