scripts: Do not create the config directory.
This fixes runs of 'guix package' and 'guix system' tests in environments where $HOME is read-only. * guix/ui.scm (config-directory): Add #:ensure? parameter and honor it. * guix/scripts.scm (warn-about-old-distro): Pass #:ensure? #f to 'config-directory'.
