[PATCH 03/21] gc: use repo config

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <dstolee@microsoft.com>

The gc builtin is working towards using a repository pointer instead of
relying on the_repository everywhere. Some of the instances of
the_repository are hidden underneath git_config...() methods. Expose
them by using repo_config...() instead.

One method did not previously have a repo equivalent:
git_config_get_expiry().
