Pull request: test: account for truthy signal in flaky async_hooks tests

When the spawned child process gets closed with a signal, the exit code is not set and that is why the exit code assertion was failing. This change adjusts the test to check the signal and if it is truthy, it doesn't assert the exit code and instead logs the signal and continues the rest of the assertions.
