Support 16+4 mouse buttons within the generic/evdevmouse plugin.

Browse Source 
The Kernel's evdev module is capable of presenting up to 16 mouse
buttons, plus wheel events (UP, DOWN, LEFT, and RIGHT). This
patch updates our Plugin, so that it tranlates all of those button
numbers into corresponding MouseEvent Qt::MouseButton values.

Task-number: QTBUG-24590
