description:
Fix inverted Y-axis value passed to wsmouse_input(9).

Note this is what src/sys/arch/macppc/dev/ams.c does as
"upward (moving the mouse forward) is positive" as noted in wsmouse(9):
 http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/macppc/dev/ams.c#rev1.4

Reported and tested by @NonameInsect on his SE/30 and Xorg server.
Should be pulled up to netbsd-8 and netbsd-9.
