Add sslib master tox build + flesh out test docs

Add a tox build that runs tests against securesystemslib's tip of
development, i.e. master branch, to ease preparation of tuf for a
new securesystmeslib release.

The tox build is run on travis but is allowed to fail.

This commit also fleshes out the testing section of the
contribution documentation.
