Fix devices information struct in container

So far nowhere use the ```Devices``` which in ```RunContainerOptions```. But when I want to use it, found that it could be better if change it, because Devices in container is like:
```json
"Devices": [
                {
                    "PathOnHost": "/dev/nvidiactl",
                    "PathInContainer": "/dev/nvidiactl",
                    "CgroupPermissions": "mrw"
                },
                {
                    "PathOnHost": "/dev/nvidia-uvm",
                    "PathInContainer": "/dev/nvidia-uvm",
                    "CgroupPermissions": "mrw"
                },
                {
                    "PathOnHost": "/dev/nvidia0",
                    "PathInContainer": "/dev/nvidia0",
                    "CgroupPermissions": "mrw"
                }
            ],
```
