[PATCH v2 2/2] gitlab-ci: add an ARM32 qemu-based smoke test



Add a minimal ARM32 smoke test based on qemu-system-arm, as provided by
the test-artifacts qemu container. The minimal test simply boots Xen
(built from previous build stages) and Dom0. The test is fetching the
Dom0 kernel and initrd from Debian Jessie: they work just fine and this
way we don't have to maintain a build for them too.

Signed-off-by: Stefano Stabellini <stefano.stabellini@xxxxxxxxxx>

---
Changes in v2:
- improve comments
- don't limit dom0 cpus
- decrease mem to 1024M and dom0_mem=512M
- use Debian Bullseye instead of Jessie
