[PATCH 17/12] CI: Refresh Ubuntu Focal container as 20.04-x86_64

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Exactly as per 18.04 (Bionic).  This saves ~500M:

  registry.gitlab.com/xen-project/xen/ubuntu    20.04-x86_64           1.06GB
  registry.gitlab.com/xen-project/xen/ubuntu    focal                  1.57GB

Runs with the new container:

  4.16: https://gitlab.com/xen-project/people/andyhhp/xen/-/jobs/7323548811
  4.19: https://gitlab.com/xen-project/people/andyhhp/xen/-/jobs/7323517116
