Fix cron-ci failures: ctypes set_attr, missing features, __func__ AttributeError

- Use cls.set_attr() instead of cls.as_object().set_attr() in ctypes
  to ensure modified() is called and type cache stays valid
- Add host_env feature to cron-ci.yaml for frozen_origname_matches test
- Add stdio feature to cron-ci.yaml for encodings initialization
- Fix __func__ AttributeError in custom_text_test_runner.py
