test: skip test-child-process-stdio-reuse-readable-stdio on Windows

It is flaky due to the same cause of test-child-process-pipe-dataflow
being flaky - cygwin quirks - so skip it on Windows too.

Drive-by: remove the skip mark of test-child-process-pipe-dataflow
in the status file and directly skip it in the test with a comment.
