Subject: [PATCH v2] checkpatch: don't complain on _Generic() use

Improve CamelCase recognition logic to avoid reporting on _Generic() use.

Other C keywords, such as _Bool, are intentionally omitted, as those
should be rather avoided in new source code.

Signed-off-by: Przemek Kitszel <przemyslaw.kitszel@...el.com>

v2: _Static_assert dropped from the scope;
    whole word match.
