scrolledwindow: Show scrollbars on tablet devices

The code managing scrollbars visibility was too pervasively checking for
mouse devices, leaving pen/eraser/cursor devices with no scrollbars at
all. Relax these checks a bit, and actually toggle full-width scrollbars
on pen/eraser devices, so it is an easier target.
