* [kunlun] fix the dataloader problem in RDMA env

When running multi-machine training with Paddle DataLoader, an
unexpected segmentfault will be raised in DataLoader Process,
where the traceback goes all back to a runtime error that dataloader
workers exit unexpectedly. Similar problems have been discussed
that lead to a misbehavior of OpenCV working in multiprocessing
environment.
