Subject: [PATCH] makekeys: handle the new _EVDEVK xorgproto symbols

These keys are all defined through a macro in the form:
   #define XF86XK_BrightnessAuto		_EVDEVK(0x0F4)

The _EVDEVK macro is simply an offset of 0x10081000.
Let's parse these lines correctly so those keysyms end up in our
hashtables.
