Use transaction file triggers to configure plugins

Because ldconfig is now run as a trigger, and creating the plugin
configuration requires loading the plugins which depend on graphviz's
own libraries, these too should also be triggers.  This also simplifies
the spec file, and is in line with how plugin cache generation is
handled in other packages.
