    configury: let python3 be python3
    
    Our baroque heuristics for identifying python2/3 under their various
    historical aliases is showing its age.  On some modern distros,
    /usr/bin/python is to be positively NOT used.  Fixing configure.ac
    $PYTHON3 search to only look for python3, and not even consider
    $PYTHON_UNKNOWN.  At some point we'll want to simplify further, and
    get rid of python2 remnants.
