[PATCH libinput 8/9] test: loosen up litest to allow major/minor handling

[Peter Hutterer]

The max values on ABS_MT_TOUCH_MAJOR/MINOR aren't hard limits, they basically
represent the size of a finger with (afaict) a suggestion that anything
greater than the max may be a palm. Disable the 0-100% range checks for those
axes so we can send custom events.
