Upgraded til 0.34.x broke my deployment

On April 1st (no fool!) I ran a long overdue upgrade on my Debian Linux, which bumped my Dokku from 0.32.4 to 0.34.2 and it immediately killed my running Django site. After trying to start and rebuild, I kept getting `Operation not permitted` errors when the process was trying to `chown`. Looking at the changelog, some stuff relating to this was definitely changed.

Example of the error would look like this: `chown: changing ownership of '/app/.release': Operation not permitted`.

Also, trying to rebuild through the git receiver gave the same error.

Through apt, I've now downgraded to 0.33.9 and everything builds and runs fine again.

I lost some of the output for this as I was focus on getting this site up again for a client (an old legacy site that's not super important, but still needs to be up).
