avoid unicode character that messes up pod rendering

[rajatchopra]

Description

When using the '<' character, the script is rendered like this:
if [ \"$(\u003c/run/nvidia/validations/workload-type)\" != \"vm-passthrough\" ]; then echo kata not needed, skipping validation; exit 0; fi;

This PR changes the < to cat so that the init check is functional.

What about Line 49? Why is this issue only being discovered now? We have the same entrypoint scripts in the kubevirt-gpu-device-plugin and no one has reported issues. https://github.com/NVIDIA/gpu-operator/blob/main/assets/state-sandbox-device-plugin/0500_daemonset.yaml

Also note, based on the PR description I believe you intended to update https://github.com/NVIDIA/gpu-operator/blob/main/assets/state-kata-device-plugin/0500_daemonset.yaml?
