environment: make `get_git_dir()` accept a repository
The `get_git_dir()` function retrieves the path to the Git directory for `the_repository`. Make it accept a `struct repository` such that it can work on arbitrary repositories and make it part of the repository subsystem. This reduces our reliance on `the_repository` and clarifies scope.
