Cirrus: Prevent resident pollution
When constructing VM cache-images, the latest/greatest podman package is installed to ensure all necessary dependencies are met. Prior to testing source-built binaries, most of of the packaged files are removed. However, if the `io.podman` service or socket is enabled/running, it could cause the packaged podman and varlink binaries to be both resident and cached. Since this condition would cause very difficult to diagnose behaviors, add preventative measures to ensure these services are absent prior to removing packaged podman files.
