Subject: [PATCH] configure: Fix Graphviz test and input generation.

This check for Graphviz never actually worked properly because Autoconf
swallows up the [] around [gG], so Graphviz was always detected as missing.
This commit fixes the problem by doubling up to [[gG]].

Because Graphviz was never used, I never noticed that ovsdb-dot had not
been revised to use the latest Python interface to OVSDB, so this commit
fixes up those problems too.
