Currently, QEMU's iotests rely on /usr/bin/env to start the correct Python (that is, at least Python 2.4, but not 3). On systems where Python 3 is the default, the user has no clean way of making the iotests use the correct binary. This commit makes the iotests use the Python selected by configure.
