uvc-gadget: Dynamically watch/unwatch uvc device fd
When the uvc device fd is put on the watch list statically, then there are many "Unable to dequeue buffer: Invalid argument (22)." because the V4L2 API returns write events immediately when the stream is off. To fix this, add the fd to the watch list on streamon, and remove it on streamoff.
