make test: automatic "vpp finishes startup" check
Add code which checks if vpp doesn't crash/exit immediately after startup to aid debugging stuff like mistyped graph node name or so. Refuse to run tests if the vpp is unable to start, complain loudly and print vpp's stderr at critical log level if this happens to make spotting these problems in jenkins easy.
