Cherry-pick 29c905a152b5cbc8ab67b2cc758ef3f7c8f58d88 from upstream

[github-actions]

This is an automated cherry-pick by gitstream of 29c905a152b5cbc8ab67b2cc758ef3f7c8f58d88 from https://github.com/kubernetes-sigs/kernel-module-management.

Commit message:

Restrict device plugin hostPath volumes to allowed prefixes

Add webhook validation that rejects hostPath volumes in
spec.devicePlugin.volumes unless the path resolves under /dev, /sys,
/var or /opt. This prevents device plugins from mounting arbitrary
host directories such as / or /etc.

Hi @github-actions[bot]. Thanks for your PR.

I'm waiting for a rh-ecosystem-edge member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
