The libbpf CI always builds the kernel from source at CHECKPOINT-COMMIT;
there is no prebuilt-kernel matrix entry. Remove the `kernel` input and
the conditional build-vs-download logic, simplifying the workflow.
The run-vmtest action defaults KERNEL to "LATEST" internally when the
env var is unset, so DENYLIST-LATEST is still picked up. The vmlinuz
path is auto-discovered via `make -s image_name` when not passed.
