 tox.ini: use --editable to work around old-pip bug

 One of the buildslaves (Ubuntu wily 15.10) has a very old pip-1.5.6,
 which doesn't know how to "pip install" a filepath+extra (like
 ".[test]") unless --editable is also used.

 It's convenient to have --editable set anyways (so you can do subsequent
 narrow testing without re-running tox, by running ".tox/py27/bin/trial
 TESTCASE" or use .tox/py27/bin/activate), so changing the dependency
 from ".[test]" to "--editable=.[test]" is the easiest way to work around
 that older buildslave. (I could also have upgraded the buildslave to use
 a newer pip, but 15.10 is pretty recent and other people will probably
 hit this too, so this way it's fixed for everybody).
