Cirrus: Use Makefile for image-building

The packer tool takes JSON as input for the details of producing VM
images to be used for PR CI-testing.  JSON is not a very human-friendly
format, without support for comments and frequently containing lots of
duplicate data.

Fix this by using a Makefile + simple python one-liner to convert
from a human-friendly YAML format into packer-native JSON.  This allows
use of anchors/aliases to reduce duplication, and allows inline comments
for easier maintainability.  This also allows separating the 'test'
action from the 'build' action, for earlier and better syntax problem
detection.

Lastly, there are some minor ``lib.sh`` and ``integration_test.sh``
updates to support future work, and slightly improve the build and
test environments.
