This isn't right.

We have either one or two images.  If this is a new user fork,
we only have the $COMMON_TAG image in the main QEMU registry.
If this is a existing fork, we might have two images, one in
the main QEMU registry and one in the user's fork registry.
Both of the images are to be used as a cache source, with
the container tools figuring out which has matching image
layers, if any.

This proposed change makes TAG and COMMON_TAG identical
which means we loose inheritance from the main QEMU
registry, which almost always has suitable cached content.

Again this is wrong.

I'm not sure about this one though.
