[FIX] Possible fix for broken TestManifestInclusion suite (- WIP #131 -)

Changes in file Makefile:
 - target "test" now depends on MANIFEST.in
 - target "test-pytest" now depends on MANIFEST.in and test-reqs
 - target "test-tox" now depends on MANIFEST.in through build (no change was needed)

Changes in file tests/test_manifest.py:
 - removed debugging from "test_sdist_includes_required_files"
