Thanks again !

You don't. If the vdex file of a system app doesn't contain any dex/cdex files, that means the app already has its classes*.dex files included in the APK. Which is exactly the case in your sample file: Launcher-release-signed.apk already contains classes.dex and classes2.dex, so no deodexing is needed, and the oat directory can be simply removed.
