tests: Add docker/dmesg logs in after_case for CLH test

Collect journalctl docker logs and dmesg log for CLH test
under after_case

Sometime, we miss the dmesg logs because of serial console
as we collect dmesg only if serial console is not there.
For baremetal run, serail console logs are not whole and
we miss the logs.
