[gtk-vnc] Don't short-circuit request for TLS credentials

[Daniel P. Berrange <dberrange src gnome org>]

    Don't short-circuit request for TLS credentials
    
    Although newer GNUTLS has a default system trust fallback for CA
    certificates, we must still request certificates from the client app. If
    we do not, then the VNC client will never be given the opportunity to
    provide custom certs to override the system trust database.
