[pgpool-committers: 9294] pgpool: Test: skip the test if there's no test.sh.

[Tatsuo Ishii]

Test: skip the test if there's no test.sh.

This is useful when developers want to run the test on git repository
because the check suppresses false positive errors. There could newer
branch's test directories remain without any contents and regress.sh
reports wrong failures.

Branch
------
V4_0_STABLE
