playbook: Fixup support to debian 9 with a workarround

  Unfortunally exising keys from open build service uses 1028-bit keys and debian 9 seems not reconize is as
  security enough, so on debian 9, we allow insecure repositories to allow re6st-node package be installed.

  This change can be re-worked in order to make the repository valid again.
