Add podman machine test suite

This PR introduces a test suite for podman machine.  It can currently be
run on developers' local machines and is not part of the official CI
testing; however, the expectation is that any work on machine should
come with an accompanying test.

At present, the test must be run on Linux.  It is untested on Darwin.
There is no Makefile target for the test.  It can be run like `ginkgo -v
pkg/machine/test/.`.  It should be run as a unprivileged user.
