Ensure yum failures in with-loop result into a failed task

The implementation is fairly simple, we force the rc= parameter to not be zero so that the check in _executor/task_result.py_ correctly determines that it failed. Without this change Ansible would report the task to be ok (despite failed=True and msg=Some_error_message) although Ansible stops and the summary output reports a failed task.

This fixes #4214, #4384 and also relates to ansible/ansible#12070, ansible/ansible#16006, ansible/ansible##16597, ansible/ansible#17208 and ansible/ansible#17252
