add: nvidia-cdi-hook to nvidia-container-toolkit

[isaac-400]

Issue number:

Closes # N/A

Description of changes:

Downstream users want to use the base nvidia-container-toolkit package with CDI. For full CDI support, the nvidia-container-toolkit package should include the nvidia-cdi-hook. The hook nvidia-cdi-hook is the CLI tool that is expected to be called by the container runtime, when specified by the CDI file.

For more information about how this hook is packaged by NVIDIA, see the official RPM 1.
For how the CDI hook interacts with the container runtime, see the CDI hook documentation 2.

Testing done:

Before this change, running nvidia-ctk cdi generate includes the following log message:

...
WARN[0000] Failed to locate nvidia-cdi-hook: pattern nvidia-cdi-hook not found
...

Nit: we typically list the package first in the commit message and then the change so it should be "nvidia-container-toolkit: add nvidia-cdi-hook" for the first line. Otherwise the code looks good to me!
