AppImageLauncher exports DESKTOPINTEGRATION even after X-AppImage-Integrate=false makes it skip the AppImage. AppRun treated that variable as "already integrated" and wrote no .desktop file, so the menu stayed empty. Skip our entry only when another .desktop file's Exec already points at this AppImage.
