[libvirt PATCH 07/11] ci: helper: Improve output for list-images action

[Andrea Bolognani]

This makes the output more compact by grouping together all
images that are built on the same base OS.

Later on, when we change the actions that operate on
container images to accept an lcitool-style --cross-arch
argument instead of expecting the name of the image to have
the cross-building architecture baked in, this will allow
users to quickly copy-and-paste the necessary information.
