setup.py: Add plugin requirements as extras

Currently, there isn't an easy way to install BuildStream along with its
plugin dependencies, using pip.

Add plugin requirements as extras
(https://setuptools.readthedocs.io/en/latest/setuptools.html#declaring-extras-optional-features-with-their-own-dependencies)
so that they can be installed by specifying the relevant extras to
`pip`.

This repository has only one plugin - `deb` source - that has external
dependencies, i.e. `arpy`. With this patch, one should be able to
install BuildStream and dependencies for the `deb` plugin using
something like `pip instal BuildStream[deb]`.
