[Buildroot] make graph-build : missing dot host dependency

Hi

While trying one of the new graphs features :

# make graph-depends
/bin/sh: line 2: dot: command not found

There seem to be some host tools and libs missing for this feature to work.

Yes, you need to have installed on your host system (Debian packages
names):
  - for graph-depends:
    - graphviz (for dot)
  - for graph-build:
    - python-matplotlib or python3-matplotlib
    - python-numpy or python3-numpy
    - argparse if python < 2.7

We could add a check that these tools are present, before running the
graph stuffs. Care to look into that?
