Cirrus: Reveal magic, parallel system-testing

Previously, several magic strings were in place to affect cirrus-ci
operations.  Two were buried within scripts.  One to optionally
execute system-tests within a PR. Another to avoid re-building
cache-images upon every merge.

Move these magic strings out into the open, buy locating their
logic up-front in the ``.cirrus.yml`` file.  This improves
readability and reduces surprise/astonishment at runtime.
