This change reverts the following previous change:
These can be useful, but were probably left in past the point where they
are always useful:

- https://github.com/flutter/flutter/pull/58018
- https://github.com/flutter/flutter/pull/56342
- https://github.com/flutter/flutter/pull/74080

... compared to the cost of reading these logs with 1000s of lines of
`stdout: ` output.

Will ask the CI gods if any of this was load-bearing before sending out
for review.
