Per discussion on #53893, go test -json should only print JSON to stdout.
We should ensure that's true.

Change https://go.dev/cl/529120 mentions this issue: cmd/go: avoid writing non-JSON "build failed" errors from 'go test -json'

In 'go test -json' we expect stdout to contain only JSON events,
not unstructured text. Unstructured text should either go to stderr
or be wrapped in a JSON event.

(If we add structured build output in #62067, we can emit this output
as a build event instead of a test event.)

Fixes #35169.
For #54378.
