tzutils: tzdata provides python3-tzdata and py3:tzdata

according to the Python documentation[1], the `zoneinfo` module uses the
system timezone data if available, and also provides an installable `tzdata`
library on PyPi. Some Python packages (like pandas) spuriously always
depend on this library. By having `tzdata` provide this py3: package,
it would work around Python packages that make this mistake, and avoid
needing to package `python3-tzdata` or set `noverifypydeps` (which would
be overkill).
