Zathras reports failed tests as successful

[grdumas]

I experienced a test wrapper failure which was reported in the run output, but the final status line reported that all tests succeeded.

Failure detected in output:
TASK [test_generic : We failed] ************************************************
ok: [perf-intel-23] => {
"msg": "//root/workloads/autohpl-wrapper-1.23/auto_hpl/build_run_hpl.sh reported failure."
}

Final output line reports all tests succeeded:
All tests executed sucessfully

The expected behavior is that test failures and successes would be accurately and consistently reported.
