In the preceding commit we refactored how we load multi-pack indices to take a corresponding "source" as input. As part of this refactoring we started to store a pointer to the MIDX in `struct odb_source` itself.

Refactor loading of packfiles in the same way: instead of passing in the object directory, we now pass in the source from which we want to load packfiles. This allows us to simplify the code because we don't have to search for a corresponding MIDX anymore, but we can instead directly use the MIDX that we have already prepared beforehand.
