[pgpool-committers: 7258] pgpool: Doc: fix log_standy_delay description.

[Tatsuo Ishii]

Doc: fix log_standy_delay description.

The description failed to explain actual behavior when
log_standy_delay = always is set. In fact it does not log if the
streaming delay is not greater than 0. Also added that 'none' is the
compiled default. Removed duplicate description in Japanese doc.
