Force a button if MT axes are present and it is not a gamepad
We expect at least BTN_TOUCH for anything with MT axes, but devices that
don't have that need a button class regardless. Some gamepads define
MT axes but no buttons, causing a bug in the server when they post a
TouchBegin.
[ 97436.293] (EE) BUG: triggered 'if (!b || !v)'
[ 97436.293] (EE) BUG: exevents.c:929 in UpdateDeviceState()
So, ignore it, if it is a joystick (e. g. if it have BTN_JOYSTICK defined).
Otherwise, fake a button.
This patch basically merges two patches written by Peter Hutterer
