WeTek_Core/WeTek_Play: set video state to disabled on boot

Browse Source 
right after boot, if a hardware decoded video is not yet played, asking
/dev/amvideocap0 for a frame results in -EAGAIN after a short delay.

hyperion is doing AMSTREAM_IOC_GET_VIDEO_DISABLE ioctl on /dev/amvideo
to check if video is playing. if initial state is not set, hyperion gets
confused, resulting in leds lagging until a hw decoded video is started.

this allows hyperion's regular framegrabber and amlgrabber to co-exist nicely
