nvidia-container-toolkit: update to v1.19.1

[vigh-m]

Description of changes:

• Update nvidia-container-toolkit, libnvidia-container, and k8s-device-plugin to v1.19.0. This change brings in a new hook DisableDeviceNodeModificationHook when using CDI mode.

  From the PR in nvidia-container-toolkit:

   This change adds a hook to disable device node creation for FULL GPUs (i.e. non-MIG devices) or 
   modification in a container by updating the ModifyDeviceFiles driver parameter.
  
   (This does not include nvidia-caps devices that are required by MIG devices).
  
   The presence of "extra" device nodes in a container are largely cosmetic since the container should 
   not have the required cgroup access for the additional devices. This does not affect the device 
   nodes on the host.
  

This new hook looks safe to update based on the above and testing done.

Testing done:

• Tested Nvidia workloads in cdi-cri mode and volume-mounts mode, with and without MIG enabled.
• Validated testing the new mofedEnabled: false by launching pods on EFA enabled instances
