Fix apparent typo in make create-update-info

157298bb808a943616991927f9370a86c1f2ca48 "android and bin/update: make pythonic"
had introduced this apparent typo, so that `make create-update-info` would now
fail (and no idea if that make target would still do anything useful, beyond
this initial hurdle)
