    ping: fix listing test cases when scapy is not installed
    
    The ATF-python test program was attempting to list test cases that
    require scapy.  But it attempted to import the scapy module before the
    test cases had been listed, resulting in an ImportError that kyua
    interpreted as a test program crash.
    
    Fix this behavior by handling that ImportError well enough to list test
    cases, but not run them.  If scapy isn't present, Kyua will refuse to
    run the test cases.  But it needs to be able to list them in order to
    know to skip them.
