[PATCH evdev] Map REL_DIAL to horizontal scrolling (#73105)

[Peter Hutterer]

This was the original behaviour introduced in
f77410e1f97d394e98c854fd174f712666b0544c and stayed that way until smooth
scrolling erroneously added it as vertical axis in
b450efdf95999cad08de23ce069f04a66bdae24b. Revert to horizontal scrolling to
restore the previous behaviour - which unbreaks scrolling on Microsoft mice.
