Input: ALPS - fix trackstick button handling on V8 devices

BugLink: http://bugs.launchpad.net/bugs/1677589
commit 47e6fb4212d09f325c0847d05985dd3d71553095 upstream.

Alps stick devices always have physical buttons, so we should not check
ALPS_BUTTONPAD flag to decide whether we should report them.
