    app/tests: Run tests on an Xvfb X server if available
    
    Add a configure check for xvfb-run and run tests with that if
    available. This makes it possible to easily run UI tests in headless
    environments such as a server that does nightly builds; one just needs
    to make sure xvfb-run is available.
