Make the package Red Hat Enterprise Linux friendly

Red Hat Enterprise Linux doesn't provide as much packages as Fedora.
python-networkx is just a setools dependency in Red Hat Enterprise
Linux and needs only limited set of functionality covered by small set
of requirements.

- BuildRequires are limited to necessary minimum and pytest is skipped
  in Red Hat Enterprise Linux

- -doc subpackage is not built for Red Hat Enterprise Linux
