Subject: [PATCH] openbsd.sys: llvmPackages_18 -> llvmPackages_20

sys was originally pinned to llvm 18 as it failed to build with clang
19+ in 5d3564ed4c4bb0fb84f251643e1b011b379be9f4. now, it builds fine
with llvm up to 20. as we are trying to remove llvm 18 from nixpkgs, we
update this pin to llvm 20. versions 21+ still fail, but hopefully this
will fix itself, in time.
