Fix osm-common and osm-im dependencies to use v9.0

The dependencies in requirements.txt were pointing to master
instead of pointing to v9.0. With the recent changes in the
repos, osm-common and osm-im in master did not have dependencies,
so the error raised.

The file setup.py was also updated because it was enough to specify
the requirements there as 'osm-im' and 'osm-common'.
