This fixes two problems with the Azure Linux images when building runtime:

lld was failing because it didn't have zlib support

The mariner images had zlib-devel installed as a dependency of other packages (debootstrap, binutils), which no longer bring in zlib-devel on Azure Linux.
The toolchain was picking up clang-17 instead of our source-built clang-16

This was brought in by the lldb-devel package, so removing it for now. We may need to build this from source for the diagnostics repo.

@mthalman do you know why the build steps are all skipped in dotnet-buildtools-prereqs-docker-azurelinux?

The pipeline's variables were misconfigured. I've fixed it and a build is underway.
