    flatpak: Fix offline installation
    
    This commit fixes offline installation of .flatpak bundles, and fixes
    offline installation of .flatpakref files that point to a file:// URL.
    Currently such installations would be forever stuck in the "Pending
    installation..." state. The check for a file:// prefix on the
    gs_app_get_origin_hostname() return value is wrong because in case a
    file:// URL is set, "localhost" is returned. See gs_app_func() in
    lib/gs-self-test.c.
    
    One might wonder if this could be implemented by checking if
    gs_app_get_local_file() returns a non-NULL value, but
    gs_app_set_local_file() is called for flatpakref files which are not
    always offline friendly.
