    build: Disable libsocialweb backend on distcheck
    
    libsocialweb is effectively dead upstream, with no releases or
    meaningful code changes in two years. I can no longer build it on a
    modern GNOME development system, and it’s unlikely that it works as
    described any more due to changes in the web services.
    
    If users or packagers want to re-enable the backend, they will have to
    build from source with configure flags:
        --enable-vala --enable-libsocialweb-backend
    and with a Vala compiler available.
