[PATCH:xkbutils] XkbQueryExtension returns a Bool, don't use > 0 to check it

[Alan Coopersmith]

We just want to know if XkbQueryExtension returned false, so ! is enough,
don't need > 0 as well.

Reported by cppcheck:
[app/xkbutils/xkbbell.c:205]: (warning) Comparison of a boolean value
 using relational operator (<, >, <= or >=).
