Adding a --load-kmods flag to the NVIDIA OCI hook

[wk8]

Otherwise the proper kernel mods might not be loaded when trying to
stand up a container with GPUs, resulting eg in the nvidia-container-cli
command failing because /dev/nvidia-modeset wasn't around.

There performance impact of having nvidia-container-cli check for kernel
modules being loaded every time is negligible.

(as a side note, I suspect that @crosbymichael didn't hit that when writing/testing #2330 because he used https://github.com/NVIDIA/nvidia-docker on the same box beforehand - and nvidia-docker's runtime does load the mods)
