Update paths for calico/ctl and calico/node images as
  their code splitted into 2 independent projects in
  upstream. Therefore they are stored in the separate
  directories of a pipeline's workspace while building
  containers.

  This is the part of the adaptation to changes
  made in upstream repos (PROD-12401).
