pgpool: Change log_pcp_processes default to off.

Change log_pcp_processes default to off.

Previously log_pcp_processes default was on, and it could produce
excessive log lines if admins use pcp commands frequently to monitor
pgpool status. Also the log is kind of debugging message, thus it is
best to change its default value to off.
