environment: make `get_git_work_tree()` accept a repository

The `get_git_work_tree()` function retrieves the path of the work tree
of `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.
