preload failure when running cloud suite with make local-test

WHen using the qemu worker locally (not jenkins), preloading fails:

current workaround, is to change docker-compse.client.yml locally:

core:
    privileged: true # preload requires docker-in-docker
    build: core
    volumes:
      - core-storage:/data
      - reports-storage:/reports
      - /dev:/dev # required for creating losetup devices during preload
    tmpfs:
      - /var/run # use tmpfs docker-in-docker pid files
      - /var/lib/docker use tmpfs for docker-in-docker data root
    restart: 'no'

Moving the /dev:/dev bind mount away from the devices attribute of the yml file

I'm not sure why this works yet
