configure: Insist on a Python 2, not Python 3
Our Python scripts require Python 2 and will fail on Python 3, eg:
File "/home/petmay01/linaro/qemu-from-laptop/qemu/scripts/qapi-commands.py", line 378
except getopt.GetoptError, err:
^
SyntaxError: invalid syntax
Add a check to configure that Python is not a Python 3, so we can
fail with a comprehensible error rather than an obscure one.
