    screensaver-proxy: Support the KDE interface as well
    
    KDE uses the non-namespaced interface path "/ScreenSaver" instead
    of the correct "/org/freedesktop/ScreenSaver":
    
https://projects.kde.org/projects/kde/kde-workspace/repository/revisions/100c4ccc/entry/ksmserver/screenlocker/interface.cpp#L51
    
    So support that as well...
