fix: possible timing issue in utility-process spec (#45690) This fixture has been calling process.exit() immediately after writing to stdout and stderr, which the Node.js docs say is risky behavior: > Calling process.exit() will force the process to exit as quickly as > possible even if there are still asynchronous operations pending that > have not yet completed fully, including I/O operations to > process.stdout and process.stderr. This fixture's been around for years without problems (AFAIK). The writes are very small ('hello\n' and 'world') and finish quickly. But recently I've been testing on a very slow CI machine. There, I see this spec flaking when it expects stderr to be 'world' but it gets ''. This PR changes the fixture to wait for stdout & stderr to flush before calling process.exit(). 2025-02-20 05:28:04 +00:00			`function write (writable, chunk) {`
