Rusty Russell 06a54606a3 check-includes: allow redundant "config.h"
We should actually be including this (as it may define _GNU_SOURCE
etc) before any system headers.  But where we include <assert.h> we
often didn't, because check-includes would complain that the headers
included it too.

Weaken that check, and include config.h in C files before assert.h.
