git_config_colorbool: refactor stdout_is_tty handling
Usually this function figures out for itself whether stdout is a tty. However, it has an extra parameter just to allow git-config to override the auto-detection for its --get-colorbool option. Instead of an extra parameter, let's just use a global variable. This makes calling easier in the common case, and will make refactoring the colorbool code much simpler.
