copr-be: fix Ansible deprecation warnings

[DEPRECATION WARNING]:
"include" is deprecated, use include_tasks/import_tasks instead. See
https://docs.ansible.com/ansible-core/2.14/user_guide/playbooks_reuse_includes.html
for details. This feature will be removed in version 2.16. Deprecation
warnings can be disabled by setting deprecation_warnings=False in
ansible.cfg.
