configure: Allow (and prefer) Python 3

Our build process no longer depends on Python 2, so we can
finally allow Python 3 to satisfy our requirement for a Python
interpreter.

Since several distributions have now switched to installing
Python 3 by default and Python 2 is on its way out, prefer the
former when both are available.
