[PATCH v4 05/12] pack-check: stop depending on `the_repository`

[Patrick Steinhardt <ps@pks.im>]

There are multiple sites in "pack-check.c" where we use the global
`the_repository` variable, either explicitly or implicitly by using
`the_hash_algo`. In all of those cases we already have a repository
available in the calling context though.

Refactor the code to instead use the caller-provided repository and
remove the `USE_THE_REPOSITORY_VARIABLE` define.
