There's two callsites which assemble global config paths, once in the config loading code and once in the git-config(1) builtin. We're about to implement a way to override global config paths via an environment variable which would require us to adjust both sites. Unify both code paths into a single `git_global_config()` function which returns both paths for `~/.gitconfig` and the XDG config file. This will make the subsequent patch which introduces the new envvar easier to implement. No functional changes are expected from this patch.
