send-pack: stop using the_repository

Stop using `the_repository` in the "send-pack" subsystem by passing in a
repository when sending a packfile.

Adjust callers accordingly by using `the_repository`. While there may be
some callers that have a repository available in their context, this
trivial conversion allows for easier verification and bubbles up the use
of `the_repository` by one level.
