ftbfs against python3-django 3:4.2.4-1

[Bryce Harrington]

senlin-dashboard is failing to build after a minor Debian update. The update performs a more aggressive cleanup, to address a prior ftbfs in Debian; however it isn't clear that is the cause of this failure.

Of note, Debian builds against the older 3.2.20 version of python3-django, whereas we build against the newer 4.2.4. It is not obvious if that is the cause of the failure either, but seems more plausible.

As a note, masakari-dashboard appears to be a similar situation. Different error messages, but also started failing after a seemingly minor cleanup change, and Debian doesn't build the package against the newer Django.
