Skip graphics modifier in CSV mode

In CSV mode the CSV files at /etc/nvidia-container-runtime/host-files-for-container.d/
should be the source of truth for container modifications. This change skips graphics
modifications to a container. This prevents conflicts when handling files such as
vulkan icd files which are already defined in the CSV file.
