Add graphviz install trigger

graphviz utilitizes a plugin cache which needs to be created once
installed.  While graphviz does have its own %post to do so, when built
in /app it does not work because it first requires ldconfig to be run
(so that the plugins can resolve graphviz's own libraries).

graphviz's %post has been converted to a trigger in rawhide (F40), but
in the meantime for F39, this avoids the issue.
