Migrate: Add support for auto-migrate default setup (bug #7478).

If XFCE_PANEL_MIGRATE_DEFAULT is defined in the environment
and no old 4.6 config is found; the panel will skip the
migration dialog and try to migrate the default setup.

Also skip the dialog if neither an old or default config is found.
