Subject: [PATCH] run-vmtest: set no5lvl for the VMs

There are flaky boot crashes on BPF CI:
* https://github.com/kernel-patches/bpf/actions/runs/27271262414/job/80542509369
* https://github.com/kernel-patches/bpf/actions/runs/27260143782/job/80505353689

They seem to disappear with 5-level paging turned off.

Add no5lvl to the boot params to mitigate.
