description:
Fix a test that has been (unnoticed) failing ever since printf(1) was
changed to exit(1) when it detects a write error to stdout.

Running printf with stdout closed is guaranteed to generate such a
condition.

Until the previous commit, while the test case was actually failing
(stderr was expected to be empty. and was not) this was unnoticed.
We don't want the output (obviously), we also don't want the error
message, so just direct the latter to /dev/null.
