[v29.9.0-rc.1 regression] e2e: TestRunAttachedFromRemoteImageAndRemove failing with v29.9.0-rc.1

[thaJeztah]

The e2e failure is unrelated, but looks like a genuine failure with the v29.9.0-rc.1 daemon; at a quick glance, it's either a race, or a bugfix that caused the output to change (need to check), combined with a test that may be too strict;

• could be related to daemon/containerd: Always fetch missing layer content moby/moby#53615

This needs a fix in the daemon probably;

OK; steps to reproduce;

docker run -d -q --name reg -p 127.0.0.1:5000:5000 registry

docker pull -q alpine

docker tag alpine 127.0.0.1:5000/alpine:test-run-pulls

docker push -q 127.0.0.1:5000/alpine:test-run-pulls
127.0.0.1:5000/alpine:test-run-pulls

docker rmi 127.0.0.1:5000/alpine:test-run-pulls

On v29.8, pulling that image;

On v29.9, an extra progress output is shown;
