[tor-relays] do not run Tor client and OR relay together!

Anyone who has configured a Tor SOCKS5 client to run in a 'tor' instance that also operates as an OR relay should isolate the client to a separate client-only process. The client function disturbs relay traffic forwarding in a manner that lends itself to confirmation analysis. See bug 16585, particularly comment 5 and onward: https://trac.torproject.org/projects/tor/ticket/16585#comment:5 Perhaps read comment 10 first.
