Avi Kivity 67a0c865cf tools: toolchain: prepare: don't overwrite existing images
The docker/podman tooling is destructive: it will happily
overwrite images locally and on the server. If a maintainer
forgets to update tools/toolchain/image, this can result
in losing an older toolchain container image.

To prevent that, check that the image name is new.

Closes scylladb/scylladb#15397
