I appreciate that these xml files already have `system.err` and `system.out` nodes, but the tooling we use doesn't expose the data here (and I cannot change that tooling). Also, the current implementation takes the first section of `stderr` or `stdout`, which is often empty and comes from the `javac` portion of the test run.

Probably, the Right Thing™ to do would be to have each jtreg `@test` represented as a junit `testsuite` and each `@run` represented as a junit `testcase` with its own status and `system-err` and `system-out` nodes (which is allowed according to https://github.com/testmoapp/junitxml). But that _is_ a much bigger change.
