Evan Lezar 35df24d63a Make handling of nvidia-ctk path consistent
This change adds an --nvidia-ctk-path to the nvidia-ctk cdi generate
command. This ensures that the executable path for the generated
hooks can be specified consistently.

Since the NVIDIA Container Runtime already allows for the executable
path to be specified in the config the utility code to update the
LDCache and create other nvidia-ctk hooks are also updated.
