containers: Adjust label commands in cockpit/ws Dockerfile to follow …

…man page example

The label commands where adjusted to contain IMAGE and NAME as env variables.
With newer podman, these are apparently just passed into the environment of the
docker run call itself, instead of being string-substituted on the command line.

See containers/podman#10192
