python3Packages.cuda-bindings: use the CUDA Python license before 13.4

Browse Source 
Releases of cuda-bindings before 13.4 are licensed under the NVIDIA
Software License for NVIDIA CUDA Python (cuda_bindings/LICENSE), which
permits redistribution subject to its distribution requirements.

Add lib.licenses.nvidiaCudaPython and accept it in
allowUnfreeCudaPredicate, so that packages depending on cuda-bindings,
such as python3Packages.transformer-engine, evaluate with the CUDA
predicate instead of requiring allowUnfree.
