[PATCH libinput] touchpad: enlarge top button area by a factor 3 instead of 1.5

[Peter Hutterer]

From: Peter Frühberger <peter.fruehberger at gmail.com>

When the touchpad is disabled, the top software button on the Lenovo T440
series touchpads currently enlarge by a factor of 1.5 (to 15mm). This is not
enough, a user has to rotate the wrist quite uncomfortable when using
the left mouse button.

When the touchpad itself is off anyway we can extend the size of the top
software buttons to the factor 3, i.e. 30mm.
