[pgpool-committers: 10562] pgpool: Test: stabilize 029.cert_passphrase regression test.

[Tatsuo Ishii]

Test: stabilize 029.cert_passphrase regression test.

When ssl_passphrase_command is not valid, the error message is
typically "bad decrypt" but it seems sometimes "wrong tag".

This is a backport of master e30bb2ead.

Backpatch-through: v4.6 - v4.2.
