Add: DPDK patch validation check

Implement DPDK version verification to ensure MTL compatibility.
This prevents runtime crashes by validating that users are
running properly patched DPDK versions.

Known limitation: Mixed environments (e.g., patched DPDK
in Docker with unpatched system drivers) can still cause
crashes, as driver-level patches cannot be detected.
