… streams. (#1694) If the _only_ thing in the `stdout` or `stderr` stream of an exit test's child process is the barrier sequence (i.e. exactly those 32 bytes and nothing else), we fail to trim it off. Fix it. Resolves #1693. ### Checklist: - [x] Code and documentation should follow the style of the [Style Guide](https://github.com/apple/swift-testing/blob/main/Documentation/StyleGuide.md). - [x] If public symbols are renamed or modified, DocC references should be updated.
