llvmPackages: Remove dead code

for hygiene

Run `deadnix . --edit`

`gccForLibs` is an argument used by multi.nix but it's an argument to
cc-wrapper, not to llvmPackages.

`@args` in `llvm/default.nix` was accidentally added in 4badff49fda90fba01684d2f19c31442688252b4

There are no uses of `@` therefore these changes are safe.
