obs-scripting: Fix Sparkle delta updates by disabling bytecode caching

Python automatically creates bytecode caches which end up inside the
application bundle of OBS Studio on macOS. These directories will lead
to a hash mismatch when Sparkle attempts to apply a delta update (to
ensure that the patch can be applied).

As the added directories will make the hash check fail, having a valid
Python framework configured in OBS Studio (even without any script
added) will thus prevent Sparkle from using delta updates.
