hwdb: redefine Lenovo ThinkPad X140e touchpad dimensions (#9818)

The default setup for the Lenovo ThinkPad X140e is 104x104mm, and the kernel
claims that it's 64x21. The default 104x104mm dimensions causes the vertical
axis to act oddly, causing random vertical jitters and higher vertical
sensitivity.

Measuring it showed that it was 74x32, and these touchpad dimensions provide
a better (if a little bit slower) experience but a consistent sensitivity
in all directions.

These values were obtained using the `touchpad-edge-detector` tool.
