[PATCH libinput] gestures: reduce the 2fg scroll timeout to 150ms

[Peter Hutterer]

This timeout is there to switch to scrolling when the fingers rest on the
touchpad unmoving and thus avoids the initial scroll threshold for slow
scrolls.

Since the only other gestures we support are swipe (usually a fast movement)
and pinch-and-rotate (also a fast movement) we can drop the timeout down
significantly and thus make the scroll feel more reactive.
