mod_auth_ccert/README: Add setting to ensure Prosdy asks for client certificate
This used to be the default for all services, but since it triggers
annoying popups in web browsers it was inverted in Prosody and only s2s
enables it, so it needs to be explicitly enabled for c2s again.
See trunk 115b5e32d960
Thanks debacle
