Add cuda 11.8 guard for cufile preload (#148184)

Browse Source 
Follow up after https://github.com/pytorch/pytorch/pull/148137
Make sure we don't try to load cufile on CUDA 11.8

Test:
```
>>> import torch
/usr/local/lib64/python3.9/site-packages/torch/_subclasses/functional_tensor.py:276: UserWarning: Failed to initialize NumPy: No module named 'numpy' (Triggered internally at /pytorch/torch/csrc/utils/tensor_numpy.cpp:81.)
  cpu = _conversion_method_template(device=torch.device("cpu"))
>>> torch.__version__
'2.7.0.dev20250227+cu118'
>>>
```
