[Docs] Fix build errors getting Deluge version

The use of pkg_resource.require caused an unwanted requirements lookup
that errored out the sphinx build when no dependencies are installed.

This is fixed by switching to pkg_resources.get_distribution.

Also changed the tox docs env to not install Deluge as the setup.py
now contains install_requires which is unwanted.
