Add ICS+DRP Dockerfile to ics_drpActor

We have a development Dockerfile for adding a few ICS products to the 2D DRP Docker image. That should be added to the `ics_drpActor` product. One unfortunate side-effect is that `pfs_pipe2d` might need to be added to the `ics_drpActor` dependencies, though I think `setupOptional` would be OK.
