opencode: incorporate upstream changes and simplify build

Remove unnecessary build customizations that are no longer required:
- Drop patch removing special build targets (fixed upstream)
- Remove preBuild hook (builds successfully without it)
- Remove fzf PATH addition (no longer needed)

Add sysctl to nativeBuildInputs on Darwin to properly detect Rosetta 2
execution environment.

Enable zsh completions by tricking yargs into generating them.
