winex11.drv: Interpret mouse 6/7 as horiz scroll.

X11 Mouse buttons 6 and 7 were set to translate into browser
back/forward button events. However, this is based on an old convention
where buttons 6 and 7 could either mean horizontal scroll or browser
back/forward. Nowadays, 6 and 7 solely mean horizontal scroll, 8 and 9
being used for back/forward. In addition, the wide adoption of
two-finger two-dimensional scrolling on laptop trackpads since this code
was written has meant that back/forward events may be generated
unintentionally, which can be very disruptive when using tools such as
web browsers.
