Switch crossbuilding to Debian 11 (#41402) (#41416)

We're dropping support for Debian 10, so no need to crossbuild using
the outdated image anymore.

The old linker in Debian 10 caused a packaging issue with some Go
dependency updates #41270

So, this update should also help with that.

This also updates the statically linked glibc from 2.28 to 2.31.

(cherry picked from commit 4140d15)
