Show deprecation/pruning candidate total

Previously, the image deprecation and pruning scripts showed the total
number of images on each system (GCE or EC2).  This is not a useful
count as it doesn't accurately reflect the backlog size of potential
deprecation/pruning images.  Fix this by operating on and showing
the total potential deprecation/pruning images in addition to the total.
