environment: make get_git_common_dir() accept a repository

The `get_git_common_dir()` function retrieves the path to the common
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.
