libx11: fix xkb compilation with _EVDEVK symbols

New xkeyboard-config writes defines that use _EVDEVK(), which makekeys
can't parse.  Take a patch from upstream to also parse these symbols.

+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.
