Fix osm-common and n2vc 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 n2vc in master did not have dependencies,
so errors can appear.

The file setup.py was also updated because it was enough to specify
the requirements there as 'n2vc' and 'osm-common'.
