Matthew Heon 2e00d417dd Migrate unit tests from cmd/podman into pkg/spec
Several changes made in the interface of pkg/spec make
interacting with it without a runtime difficult to impossible,
so move the existing limited testing from cmd/podman (which
mostly tested pkg/spec) into pkg/spec itself where we can call
individual functions that don't break things.
