config: write to $XDG_CONFIG_HOME/git/config file when appropriate

Teach git to write to $XDG_CONFIG_HOME/git/config if

- it already exists,
- $HOME/.gitconfig file doesn't, and
- The --global option is used.

Otherwise, write to $HOME/.gitconfig when the --global option is
given, as before.

If the user doesn't create $XDG_CONFIG_HOME/git/config, there is
absolutely no change. Users can use this new file only if they want.

If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/config
will be used.

Advice for users who often come back to an old version of Git: you
shouldn't create this file.
