maint: enable more checks

* cfg.mk (local-checks-to-skip): Remove exemptions
for immutable NEWS as well as the two config.h checks.
Also accept "sed.h", since the first thing it does is
to include <config.h>.
* sed/sed.h: Change "config.h" to <config.h>, for consistency
with other GNU tools.
* sed/utils.c: Likewise, here and for each of the following.
* testsuite/bug-regex10.c:
* testsuite/bug-regex11.c:
* testsuite/bug-regex12.c:
