    webcam: set force-aspect-ratio property on the videosink
    
    Almost every available gstreamer videosink can display black bars around
    the video keeping its aspect ratio. Enable it if available.
    Black bars look a lot nicer than the grey color of the underlying
    gtkwindow displayed with the aspectframe.
