I would rather reuse module_list_compute and then post-process the list
to filter out inactive submodules iff "submodule.active" is set as that seems
cleaner and performance is not a pressing issue here?

Here we also need to have
git_config(submodule_config, NULL);
such that is_submodule_initialized works correctly,
I would assume?
