    GsApp: Add get/set_origin_appstream for keeping track of appstream origin
    
    This makes it possible to store package repo origin and appstream origin
    separately. On a regular Fedora install, we have a single appstream
    metadata file (/usr/share/app-info/xmls/fedora.xml.gz) that covers all
    of Fedora repos, and doesn't have a 1:1 matching with the repo
    names.
