[PATCH 2/8] packfile: refactor `prepare_packed_git_one()` to work on sources

[Patrick Steinhardt <ps@pks.im>]

In the preceding commit we have refactored how we load multi-pack
indices so that we take take the source as input for which we want to
load the MIDX. 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 for 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.
