cuda: look for stubbed libraries too
Some libraries in CUDA are stubbed out to load the actual implementation from
the driver at runtime. One example is NVML, that only exists in `stubs/`.
Ensure that the stubs dir is searched last, like FindCUDAToolkit.cmake:
https://github.com/Kitware/CMake/blob/4f2482700b6a6231c697b1178239acf76955bfeb/Modules/FindCUDAToolkit.cmake#L1163-L1173
