    Disable building PKCS#11 backend by default
    
    This backend has never been enabled at runtime, except when the
    GIO_USE_TLS=gnutls-pkcs11 environment variable is set. I'm quite
    uncertain as to whether it should continue to exist or not. So let's
    disable it. If nobody complains, I'll probably delete the code, but
    let's keep the code around for now to be on the safe side.
