[pgpool-committers: 9360] pgpool: Test: stabilize some tests.

[Tatsuo Ishii]

Test: stabilize some tests.

069.memory_leak_extended, 070.memory_leak_extended_memqcache and
073.pg_terminate_backend uses "sleep 1" to confirm pgpool starting up,
which makes the tests unstable because there's no guarantee that pgpool
becomes ready within 1 second. Use wait_for_pgpool_startup instead to
stabilize the tests.
