    Add --first-root option
    
    This is useful in jhbuild when I often only want the tests from
    that root, rather than also running the system tests.
    
    Perhaps in the future we should optimize this further so that the
    first directory "wins" for tests rather than being merged, e.g.  the
    ostree/ tests in jhbuild win over the system root.
