v4l2: Set pixel-aspect-ratio to 1/1
We don't currently support setting the pixel-aspect-ratio from V4L2. So simply set it to be 1/1 in the caps to prevent negotiation failures when fixating to weird values (e.g. when the downstream caps has pixel-aspect-ratio = [ MIN, MAX ] ) https://bugzilla.gnome.org/show_bug.cgi?id=663580
