[PATCH libinput] touchpad: reduced the 2fg scroll threshold to 1mm

[Peter Hutterer]

At least on the t440, this is enough to trigger correct detection between
swipe and scroll 90% of the time. Since scrolling is significantly more
prevalent than gesturing, erring on the side of scrolling at the cost of
misdetecting some gestures is acceptable.
