selftests/clone3: Correct log message for waitpid() failures

broonie · shuahkh · commit 6a5695119e0a · 2024-05-06T13:57:20.000-06:00
When logging an error from calling waitpid() on the child we print a
misleading error message saying that the error we report was returned by
the chilld. Fix this to say the error is from waitpid().

Applied after fixing merge conflict:
