[libcxx-commits] [libcxx] [libc++] Install build-essential in the CI docker container (PR #185853)

[Nikolas Klauser via libcxx-commits]

https://github.com/philnik777 created https://github.com/llvm/llvm-project/pull/185853

We don't install a compiler via `apt` anymore, so we need to explicitly install the utilities required to build stuff.
