[Outreachy PATCH v2] bundle-uri: stop using the_repository

[Okhuomon Ajayi <okhuomonajayi54@gmail.com>]

unbundle_from_file() receives r and unbundles the objects into
it, but reads and writes the refs in the_repository.
fetch_bundle_uri() also has r, but uses the_repository for its
trace2 region. find_temp_filename() and copy_uri_to_file() also
use the_repository, even though their only caller,
fetch_bundle_uri_internal(), has r.

Use r in all of these places, passing it to find_temp_filename()
and copy_uri_to_file(). With that, bundle-uri.c no longer uses
the_repository, so drop USE_THE_REPOSITORY_VARIABLE.

Changes since v1:
- Also pass the repository to find_temp_filename() and
  copy_uri_to_file(), and drop USE_THE_REPOSITORY_VARIABLE,
  as suggested by Patrick.

Thanks, Patrick, for the suggestion and the diff, and Karthik
for the review.

unbundle_from_file() still depends on the_repository through
fetch_pack_fsck_objects(), which reads fetch.fsckObjects and
transfer.fsckObjects from the_repository's config.
