packaging: always pass VERSION into Inno invocation...

packaging: always pass VERSION into Inno invocation The code in the Inno file was a holdover from before we had Python driving execution. With Python in the driver's seat, we can now have it resolve the version string and pass it into Inno, making the code easier to understand for people who aren't packaging gurus.
