Merge #10672

10672: feat: upgrade ubuntu builders r=matklad a=matklad

For `-gnu` triples, use 20.04, the current LTS. This upgrades the
required version of glibc. For musl, just use `latest` as, presumably,
we don't care about glibc version in that case.

Hopefully, this unbreaks nightly publishing!
