fix: a container md5 leaves a zippedFile md5 alone

Batocera and KNULLI check a zippedFile item's md5 against the member inside the archive. A profile's container md5 for the archive would have replaced it as a correction. The item's md5 is now read as Recalbox's composite md5 is: neither compared with the container's nor overwritten by it.
