Podman creates a missing bind source instead of rejecting it, so the Docker proxy probe passed even when the daemon could not see the runner's files. Jobs of Podman runners in a container got an empty directory at `/var/run/docker.sock` (https://gitea.com/gitea/runner/issues/1193#issuecomment-1700501). The probe now binds the directory and stats its marker through the created container. A runner in a container stats the marker through its own container, so it no longer creates probe containers, which cost up to 2s per job. `make test-dind TARGET=podman` runs the probe against Podman in CI.
