[tor-qa] Test latest nightlies on Windows XP

Hi,

while testing the nightlies is always good, if you still happen to have Windows XP lying around your help is especially welcome this time. We have restructured the way the Windows bundles are built (this is essentially the Windows related part of #10120) which landed some days ago. The big question is now: Do the Windows bundles still work on Windows XP? A test would be extracting a bundle, starting it and trying to load some websites. If that still works everything is fine. The bundles can be found here:
