[PATCH:xserver 2/2] xkb: Fix case checks for Latin 8.

[Cyril Brulebois]

Spotted by -Wlogical-op:
|   CC     xkbfmisc.lo
| xkbfmisc.c: In function '_XkbKSCheckCase':
| xkbfmisc.c:104:3: warning: logical 'and' of mutually exclusive tests is always false [-Wlogical-op]
| xkbfmisc.c:118:3: warning: logical 'and' of mutually exclusive tests is always false [-Wlogical-op]

A quick look at the keysymdef.h file (from xproto) suggests the
implementor chose to use interval checks to determine the case, but
since lines weren't sorted by codepoints, checks were quite wrong.

Implement _XkbKSUpper/_XkbKSLower checks based on a grep for
CAPITAL/SMALL (respectively) on the Latin 8 part of the said file.
