The glibc Linux images are currently based on Debian bullseye, which ships CMake 3.18.4. This will be problematic once Julia upgrades to LLVM 20, which requires CMake 3.20, as noticed in JuliaLang/julia#57658.
This was worked around before by running the upgrade_cmake.sh script during build, JuliaCI/julia-buildkite#370, but that seems like a hack, and isn't feasible on PkgEval. Instead, we should upgrade the images to Debian bookworm instead, which has been out for close to 2 years now.
