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.
