[PATCH 02/15] lib-submodule-update.sh: do not use ./. as submodule remote

From

Adding the repository itself as a submodule does not make sense in the real world. In our test suite we used to do that out of convenience in some tests as the current repository has easiest access for setting up 'just a submodule'.

However this doesn't quite test the real world, so let's do not follow this pattern any further and actually create an independent repository that we can use as a submodule.

When using './.' as the remote the superproject and submodule share the same objects, such that testing if a given sha1 is a valid commit works in either repository. As running commands in an unpopulated submodule fall back to the superproject, this happens in `reset_work_tree_to` to determine if we need to populate the submodule. Fix this bug by checking in the actual remote now.
