[PATCH 14/14] Re-enable and clean up "check_config()" in headers_check.pl

I recently got bit by a CONFIG_ in userspace bug. This has apparently happened before, but the check got disabled for triggering too much. In order to reduce false positives, I added some hueristics to avoid detecting comments. Since these tests all pass, I've now re-enabled them.
