[hw/xfree86] Fix StaticGray cmap.
Fix this bug report:
,----< from http://bugzilla.freedesktop.org/show_bug.cgi?id=20504 >
| Using the Visual StaticGray (8 bit depth) is missing one gray level.
| The gray level of index zero and index one are the same and all
| other levels are shifted by one. The max level (255) cannot be used.
