[llvm] [Github] Add Zlib at build time to CI container (PR #123489)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/123489

This patch adds zlib at build time to the CI container. This is needed to make an lldb test pass that defaults to using the system lld if it is not explicitly enabled in LLVM_ENABLE_PROJECTS.

Fixes #123479 (by fixing the proximal cause).
