update how callback plugin gets copied and added to job container

when in containerized environment
- always copy callback plugin to private_data_dir/artifacts/{job_id}/callback
- appending to `ANSIBLE_CALLBACK_PLUGINS` with the runner callback plugin location (from private_data/artifacts)
- unused method `utils.callback_mount`
- update unit tests
