P1 Badge Wire kernel fragment into build

The Dockerfile now writes a configs/fragments/x86_64/dojo.conf fragment with the Landlock/BPF options, but the subsequent kernel build still runs with the default fragment set and no change to include this file. The previous Landlock tweak went straight into base.conf, which build-kernel.sh consumes, so moving the options into an unreferenced fragment means the BPF settings never reach the kata kernel and Landlock is no longer enabled.

Useful? React with 👍 / 👎.
