ci: switch integration to exec on ubuntu

- Add kitchen.exec.yml profile using exec driver/transport for localhost
- Update integration workflow to run with KITCHEN_LOCAL_YAML=kitchen.exec.yml
- Run verify against localhost with the exec profile
- Remove dokken-specific DOCKER_HOST and socat setup from CI
- Delete kitchen.dokken.yml now that CI no longer uses dokken
