It's really just a runtime dependency, which was wrong first. bzrtools
does not check for graphviz in the build, but looks for the dot tool at
runtime only.

It's arguable whether graphviz has to be a dependency or if the user
should be clever enough to understand the error message:

  bzr: ERROR: Can't find 'dot'.  Please ensure Graphviz is installed
  correctly.

In any case, adding graphviz to depends_run will issue a warning when
you accidentally want to deactivate/uninstall graphviz.
