fix logic in module host to add aliases even if none exist already, fix #4563

fix distribution detection in apt_repository module, so it also work on mint as it work on Debian, partially fix #4587

codename than the Ubuntu release it is based on, which mean that apt_repository
cannot add detect and add the proper url without a better heuristic.
