[PATCH v4 6/9] submodule: use the 'submodule--helper config' command

[Antonio Ospite]

Use the 'submodule--helper config' command in git-submodules.sh to avoid
referring explicitly to .gitmodules by the hardcoded file path.

This makes it possible to access the submodules configuration in a more
controlled way.
