fix(iso): add libnvidia-ptxjitcompiler + ldconfig for PTX JIT and NCCL

- build-nvidia-module.sh: copy libnvidia-ptxjitcompiler.so.* alongside
  libcuda/libnvidia-ml — required by cuModuleLoadDataEx for PTX JIT.
  Without it: CUDA_ERROR_JIT_COMPILER_NOT_FOUND at runtime.
  Cache check updated to force rebuild when ptxjitcompiler is missing.
- bee-nvidia-load: run ldconfig after module load so that NVIDIA/NCCL
  libs injected into /usr/lib/ are visible to dlopen() callers.
