    os-database: Load osinfo db from hardcoded path for Flatpak
    
    Libosinfo's latest release has introduced a regression causing
    osinfo_db_loader_process_default_path to fail in a Flatpak container.
    
    Until we manage to track this down and fix it in libosinfo, we can
    hardcode the path and restore the functionality. Otherwise Boxes
    crashes whenever it needs to query libosinfo (which is pretty bad).
