[RFC libinput 1/3] litest: Make touchpad_2fg_scroll_slow_distance take resolution into account

[Hans de Goede]

Currently touchpad_2fg_scroll_slow_distance always moves the touches 10% of
the touchpad height during the test.

On the wacom-intuos-finger test device this is a much larger distance then on
the synaptics test device, triggering ck_assert(axisval < 5.0) errors with
further patches in this set, this commit fixes this.
