config: clarify memory ownership in git_config_pathname()
The out parameter of `git_config_pathname()` is a `const char **` even though we transfer ownership of memory to the caller. This is quite misleading and has led to many memory leaks all over the place. Adapt the parameter to instead be `char **`.
