(PUP-3459) Pre-suite puppet bug workaround to avoid permissions errors during acceptance test.

I don't have a huge problem with this implementation; it seems like we're intentionally doing something that causes side effects, when we know what the desired side effects are and could achieve them more directly, but, @waynr you have to deal with the maintenance of this part of the code much more than the rest of us, so if this is how you want it, I'm ok with it.

It sounds like, from @haus ' comments above, that we do need another ticket to capture the fact that our packaging should be setting that directory up and permissioning it appropriately, but once that ticket is created I'm OK with this if it's still necessary.
