tools: fix type mismatch in test runner

`output.diagnostic` is a list that is appended to on SmartOS when retrying a test due to `ECONNREFUSED`. The test runner checks if `output.diagnostic` is truthy and, if so, assigns its value to `self.traceback`. However `self.traceback` is supposed to be a string, and `_printDiagnostic()` in the `TapProgressIndicator` attempts to call `splitlines()` on it, which fails if it is a list with: AttributeError: 'list' object has no attribute 'splitlines' PR-URL: #38289 Reviewed-By: Rich Trott <[email protected]> Reviewed-By: Christian Clauss <[email protected]> Reviewed-By: Luigi Pinca <[email protected]> Reviewed-By: Benjamin Gruenbaum <[email protected]>
