[PATCH] module-verifier: make it possible to run checkers on grub-module-verifierxx.c

[Peter Jones]

This makes it so you can treat grub-module-verifierxx.c as a file you can
build directly, so syntax checkers like vim's "syntastic" plugin, which uses
"gcc -x c -fsyntax-only" to build it, will work.

One still has to do whatever setup is required to make it pick the right
include dirs, which -W options we use, etc., but this makes it so you can do
the checking on the file you're editing, rather than on a different file.

v2: fix the typo in the #else clause in util/grub-module-verifierXX.c
