Subject: [PATCH] maint: prepare for using "make gnulib-sync"

* cfg.mk (cu_GNULIB_SYNC_HOOK): Add target to copy files from gnulib.
(_gl_GNULIB_SYNC_HOOK): Export variable to override gnulib's empty
default.
With this, "make gnulib-sync" (alias "update-gnulib-to-latest")
will copy the files COPYING, bootstrap and tests/init.sh from the
gnulib submodule after pulling.
