tox: add generic nobyte and numpy factors

Remove `py27-nobyte` from tox.ini, which was using xdist already.
Therefore this also removes `py27-xdist` from Travis.

"nobyte" was added in 036557ac to test that test_assertrewrite.py works
with a global PYTHONDONTWRITEBYTECODE=1 setting.

"numpy" is only a special dependency, and can be run together with
nobyte/xdist.
