Use ansible_facts variable

Without this change the "Import variables specific to distribution"
tasks fail with "Could not find file on the Ansible Controller..."
on environments with inject facts disabled.

This changes the tests to run with ansible with
inject_facts_as_vars = false and fixes other roles and playbooks.
