Fix yum integration tests (#35177)

* use tests instead of filters

* Don't check 'rc', use success/failed tests

- yum module use 'fail_json' which set 'failed'
- 'rc' is for backward compatibility:
  https://github.com/ansible/ansible/blob/bbd6b8bb42cc8fa48157ce5db0efb0a836c94917/lib/ansible/executor/task_executor.py#L571
- besides yum module doesn't document any return values

* Allow to run tests twice in a row

ansible-test is executed with '--retry-on-error' switch, then tests must
be able to executed twice in a row.

Error was:
