tox.ini: bump pyflakes version to 2.1.1 (#239)

pyflakes versions older than 2.1.0 are incompatible with Python 3.8
(which is the Python version in the current Ubuntu development release).
See https://github.com/PyCQA/pyflakes/issues/367 for details.

2.1.1 is the latest version ATM, so bump to that.
