TT#14583 Do not remove puppet code after installation

When we install puppet from git repo there will be r10k run
executed by puppuet itself and latest code fetched. We shouldn't
delete the code because after reboot puppet catalog will be empty
until someone runs r10k again. But we need catalog present because
we do another puppet run after reboot to finalize steps not executed
in chroot phase.
