    Fix container status when showing a paused containers

    We inspect a container when doing container-show, if the container is paused,
    inspect will return follows:

        "State": {
            "Error": "",
            ...
            "Paused": true,
            "Pid": 3894,
            "Restarting": false,
            "Running": true,
        },

    currently, we just mark an container object's status as Running in this case,
    but it is actually Paused.
