Restore compatibility with RHEL >= 9 for the sake of RHEL 10
    
    ... and remove Facebook, Flickr and Google support from RHEL >=9.
    
    In theory, support for Facebook, Flickr and Google is still desired.
    However, right now Facebook and Google are completely broken, and the
    Grilo code used for Flickr support has code quality issues.
    
    This reverts commit c911612d8977e5f56013250bdb59415010023b7d.
