[PATCH] docker: set timezone to Australia/Canberra

[Daniel Axtens]

The tzinfo package isn't installed in docker, which makes the
default timezone UTC. This is unfortunate: the Django TZ in
settings/base.py is Australia/Canberra, and having a non-UTC
TZ is good for exposing faulty assumptions about what is and
isn't UTC.
