getting-started: replace usage of swh-storage/sql/bin/db-init by swh-db-init

see swh-core!16 (closed) in which this swh-db-init command is added.

also add init.py files so that it's considered a true package

Test Plan

To try this i've re-installed locally swh-core and got the swh-db-init entry point. However, it fails as follows:

$ swh-db-init 
Traceback (most recent call last):
  File "/home/zack/.local/bin/swh-db-init", line 6, in <module>

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'msgpack-python' distribution was not found and is required by swh.core

even if I have msgpack installed (it loads fine in ipython3 and i can successfully run all swh-core tests).

So I'm a bit stuck testing this to approve this diff. Any tip?

The name of the Python package for msgpack has been very helpfully changed from msgpack-python to msgpack in version 0.5.0. The Debian package for python3-msgpack doesn't ship the shim that's available in PyPI itself for the transition (which means that testing this in a virtualenv works fine).

I guess this means we should migrate everything to 0.5 anyway.
