support/graph-depends: use argparse to parse argv[] 



Currently, we are using a crude, ad-hoc parsing of argv[].
This is a limiting factor to adding new options.

Use argparse instead, and introduce a single argument for now:
  --package, -p PACKAGE

In the (near) future, we'll be able to add more option arguments,
such as depth-limiting for big graphs.
