Lockscreen Shortcuts sometimes do not activate when long-pressing

When calculating the distance, the upward-scaling shortcut was affecting the getX and getY positions, causing the touchSlop to think we moved our finger too much, which cancelled the animation.

This change uses rawX and rawY as we don't want the scaling to affect the distance calculations.

Test: Manually test the lockscreen shortcuts, ensure they activate as expected
