    docs: do not try to snap a webcam pic for op gallery
    
    See bug #768917, other people have complained about the webcam turning on for a
    fraction of a second during GEGL/GIMP builds as well - so might as well exclude
    it; even if it is fun to have a randomly timed webcam image in each
    user/builders local docs :)
