Only use configured nvidia-ctk path if it is a full path

If this is not done, the default config which sets the nvidia-ctk.path
option as "nvidia-ctk" will result in an invalid OCI spec if a hook is
injected. This change ensures that the path used is always an absolute
path as required by the hook spec.
