btrfs-progs: ci: delete slow image build test workflow

The workflow defined in ci-build-test.yml builds a fresh docker image,
this could update packages that are not yet in my docker hub source image.
The purpose of this workflow is to test namely backward compatibility
(LTS distros) so there are no expected differences regarding package
versions.

There's another workflow with the same goal but based on different
docker images, that are updated on a few-weekly basis (updaed by
ci/images-* scripts). This is much faster and can be also enabled for
pull requests.

Remove the original workflow as it's not useful anymore.
