Subject: build: move coreutils-specific rules from maint.mk to new file

* dist-check.mk: New file: coreutils-specific rules extracted
from maint.mk, now that maint.mk has migrated to gnulib.
* Makefile.am (EXTRA_DIST): Add dist-check.mk.
* coreutils/cfg.mk: Include $(srcdir)/dist-check.mk.
* gnulib: Update submodule to latest.
