[PATCH] libX11: Fixing modifier key range in Xutil.h (Bug #21910)

[Bodo Graumann]

IsModifierKey, defined in include/X11/Xutil.h, is a macro determining,
which keys are regarded as modifiers. The constants ISO_Level5_Shift,
ISO_Level5_Latch and ISO_Level5_Lock where excluded previously, leaving
some Neo2 modifiers functionless in combination with compose.
This patch adjusts the range to include the correct, full range of
modifier constants.
