Subject: [PATCH] fix(nix): include libcap dependency on linux builds (#12415)

commit 923f9311215df350248e4a314e8931bfb9033bcd introduced a dependency
on `libcap`. This PR fixes the nix build by including `libcap` in nix's
build inputs

issue number: #12102. @etraut-openai gave me permission to open pr

Testing:
running `nix run .#codex-rs` works on both macos (aarch64) and nixos
(x86-64)
