To the best of my knowledge a stock Google system.img is going to be full
of Google Apps which are not part of AOSP. Things like Google Play
Services, the Play Store, and all the "Google ___" apps. Those are
installed in the system partition when they come stock which is why you
can't delete them. Your compiled system.img will not have any of those.
