Threaded.windowsCreatePipe: Set READ_ATTRIBUTES flags

Without this, the child trying to read the attributes of the stdout/stderr/stdin file (NtQueryInformationFile, NtQueryVolumeInformationFile, etc) would get ACCESS_DENIED. It's not strictly necessary on the server side of the pipe but I don't see a reason not to set it there, too.
