[MaskRCNN/PyTorch] PyTorch 1.11 breaks MaskRCNN/PyTorch benchmark build

Related to MaskRCNN/PyTorch 1.11

Describe the bug
MaskRCNN/PyTorch benchmark failed to build with PyTorch 1.11.
PyTorch 1.11 removes most of the THC headers with pytorch/pytorch#69929.
This breaks the benchmark build since there are dependencies within DeepLearningExamples/PyTorch/Segmentation/MaskRCNN/pytorch/maskrcnn_benchmark/csrc/cuda/*.

To Reproduce
Steps to reproduce the behavior:

1. Install PyTorch 1.11.0
2. Checkout https://github.com/NVIDIA/DeepLearningExamples.git
3. bash DeepLearningExamples/PyTorch/Segmentation/MaskRCNN/requirements.sh

Expected behavior
MaskRCNN/PyTorch benchmark builds successfully.

I tried similar fix as bd4cd21.
It works for PyTorch 1.11 but it will break build < PyTorch 1.11.0
