configure: automatically pick python3 is available 



Unless overridden via an env var or configure arg, QEMU will only look
for the 'python' binary in $PATH. This is unhelpful on distros which
are only shipping Python 3.x (eg Fedora) in their default install as,
if they comply with PEP 394, the bare 'python' binary won't exist.

This changes configure so that by default it will search for all three
common python binaries, preferring to find Python 3.x versions.
