[pgpool-committers: 2388] pgpool: Fix occasional failure in regression test '004.watchdog'

[Yugo Nagata]

Fix occasional failure in regression test '004.watchdog'

Switchover between pgpools sometimes fails, since the active
pgpool is stopped before the standby pgpool's watchdog is ready.
To avoid this, take a sleep before stopping the active.

The patch provided by uerhara in bug #127.
