The doc build process copies files using script/extract-content.py from
outside of the doc/ folder (specifically content in the tools/ folders).
The script was not copying graphviz directive files. This has been
fixed and the embedded graphviz directives are not (properly) stored in
separate image/*.dot files.
Note the extract-content.py file is derived from the Zephyr project.
