    flatpak: Disable BlueZ backend
    
    We figured out in libfolks that we were accidentally not properly
    requiring the `python3-dbusmock` module that is necessary for the BlueZ
    tests. We might want to be smarter about this in the future, but let's
    just lose the offending backend for now. (Note that the flatpak manifest
    doesn't even allow us to connect to the specified D-Bus interface).
