ci: Upgrade android containers from ubuntu:16.04 to 22.04

The main goal of updating to 22.04 is to get away from `llvm.allow-old-toolchain`.
These containers are not building LLVM for android, so only the host version matters.
A side benefit is that they can also use the system `cmake` instead of building one.
