This change fixes the removal of Armada images from registry.
Initially it was thought that it would only have the
airshipt/armada image, but there is also starlingx/armada-image.
To resolve this, the starlingx/armada-image key was added to
the images to be deleted.
Test Plan:
PASS Build pkgs and build image
PASS Upgrade SX stx-8 -> master
PASS When the 76-remove-armada-if-unused.py script is run
no error appears and at the end of activation no Armada
image is found.
