documentation: update tcp_accept_channel's timeout default

changed in 3.0.1 to use blocking IO instead of 1 second timeouts to
avoid getting truncated XML errors while polling gmond through WANs
or where the payload x RTT was big.

reported by Kostas while troubleshooting blocked gmond connections
in 3.1 (where the payload per host is double than 3.0)
