Update examples in README to work with current Geofabrik directory structure.

[jawlkumuna]

The OVERPASS_PLANET_URL in the first example of the README returns a 404 error, so I tried modifying it in the following way:

docker run \
  -e OVERPASS_META=yes \
  -e OVERPASS_MODE=init \
  -e OVERPASS_PLANET_URL=http://download.geofabrik.de/europe/monaco-260322.osm.pbf \
  -e OVERPASS_DIFF_URL=http://download.geofabrik.de/europe/monaco-updates/ \
  -e OVERPASS_PLANET_PREPROCESS='mv /db/planet.osm.bz2 /db/planet.osm.pbf && osmium cat -o /db/planet.osm.bz2 /db/planet.osm.pbf && rm /db/planet.osm.pbf' \
  -e OVERPASS_RULES_LOAD=10 \
  -v /overpass/overpass_db/:/db \
  -p 12345:80 \
  -i -t \
  --name overpass wiktorn/overpass-api

This seems to work, but I get some errors regarding the diffs:

Overpass container initialization complete. Exiting.

After restarting the container the output looks like this (it seems to be running, but there is still some error regarding the diffs):

Could you please update the README with a more up to date example command to help people like me get started with Overpass more easily?

Also I'm wondering why it is necessary to start this container twice in order for the API server to start working? It would be so much nicer if it could just download the data it needs, do the conversions and start running in just one go, like most other Docker images. Or am I doing something wrong perhaps?
