Motivation for this change

Building LLVM pieces is a huge contributor to build times, and probably
bloats binary size as well. Fortunately, there's a knob for this
specific thing (-DUNBUNDLED=ON seems broken and requires some libraries
which aren't packaged for Nix at the moment).

Hopefully this will make clickhouse able to build on OfBorg.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
    • Before: /nix/store/y9xf1fq0im7pj7d9xk914l5k4r88hpxi-clickhouse-20.5.2.7 786664240
    • After: /nix/store/4yii8i5ap6miyg5c6hrxas2lmr0cvp0z-clickhouse-20.5.2.7 702939080
    • ~89% in size
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

Really nice to get rid of vendored dependencies!
