Cirrus: Add podman-machine integration test

The podman-machine integration tests are designed to execute on
bare-metal, since they perform significant work with virtual-machines.
This test is costly to run at scale, so it is limited to being manually
triggered by developers (for now).  A 'trigger' button will appear in the
task status page of the Github WebUI once all test dependencies are met.
In the Cirrus-CI WebUI, there is also a 'pre-trigger' button that may be
pressed if a developer doesn't wish to wait. Also:

* Add a `localmachine` target in the `Makefile` on the off-chance
  developers wish to execute locally.  Update the `ginkgo-run` target
  to accommodate re-use by the new `localmachine` target.
* Exclude `podman_machine` task from `success` dependency verification.
  This also involves adding an exception to `cirrus_yaml_test.py`
  otherwise it will complain loudly.
* ***NOTE*** Inclusion of `ec2_instance` in *any* task will cause
  `hack/get_ci_vm.sh` to barf and be non-functional.  Future updates will
  be made to restore functionality.  Before then, simply comment out
  the `ec2_instance` section as a temporarily workaround.
