Cygwin: AF_UNIX: listen_pipe: consider STATUS_PIPE_CLOSING
NtFsControlFile(FSCTL_PIPE_LISTEN) can return STATUS_PIPE_CLOSING if a
process has already connected to the pipe, written, and closed its
handle. Treat this case the same as STATUS_SUCCESS.
FIXME: We need to check more carefully that there isn't really an
error condition.
