llm: attempt to evaluate symlinks, but do not fail (#9089)

provides a better approach to #9088 that will attempt to
evaluate symlinks (important for macOS where 'ollama' is
often a symlink), but use the result of os.Executable()
as a fallback in scenarios where filepath.EvalSymlinks
fails due to permission erorrs or other issues
