List system dependencies for running common tests

Add a bindep.txt file containing a cross-platform list
of dependencies needed for running included tox-based tests. Also
include a tox environment for convenience calling the bindep[*]
utility to list any missing system requirements, and simplify the
contributor documentation to recommend this rather than embedding an
ad-hoc list of package names in an untestable document.

This change is self-testing.
