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.
