[PATCH libinput 3/5] test: adjust the movement size for edge scroll timeout testing

[Peter Hutterer]

The goal of this test is to make sure that the deltas are less than 5, which
is the scroll trigger for movement-based edge scrolling. The litest suite
takes percentages of the device, so use a scale factor to change how far we
move on the tablet. The wacom tablet is 141mm, the movement must be smaller to
provide small-enough deltas.
