topo: make new minimal Graph object a Graph, not a DiGraph

Fixes another Graph regression relative to NetworkX.

RipL broke because the NetworkX Graph object that was used previously
for topologies is an undirected graph:

import networkx as nx
g=nx.Graph()
g.add_edge(0,1)
g¹

{0: {}}

g⁰

{1: {}}

There is a separate DiGraph object in NetworkX for directed behavior.

The minimal replacement previously implemented DiGraph behavior.

from mininet.topo import Graph
g2=Graph()
g2.add_edge(0,1)
g2⁰

[1]

g2¹

[]

This commit restores undirected graph behavior.
