Ubuntu: replace 16.04 with 22.04

Ubuntu "Jammy Jellyfish" 22.04 has been released, with long-term support
until at least 2027 (maintenance) and 2032 (extended security
maintenance).

https://ubuntu.com/blog/ubuntu-22-04-lts-released

Although ubuntu-16.04 is in Extended Security Maintenance until 2026, it
is holding us back from adding git-lfs (see
crops/yocto-dockerfiles#40).
