[pgpool-committers: 7665] pgpool: Fix watchdog_setup to not fail when -n is not specified.

[Tatsuo Ishii]

Fix watchdog_setup to not fail when -n is not specified.

watchdog_setup failed if -n (number of PostgreSQL clusters) is not
specified. Now if -n is not specified, assume "-n = 2", which is same
as in pgpool_setup.
