Check windows version in vr_pixeltests

Though the vr_pixeltests were previously removed from Windows 7 bots,
this didn't remove them from all known Windows 7 bots nor new Windows 7
bots.

Given that VR is not supported on Windows 7, we don't need to run these
tests there, so simply skip them if we're not running on Windows 7.
