Fix config.py tool according to the new API of fido2 python package (#284)

* Fix fido2 API update.

Since fido2 0.8.1 the device descriptor moved to NamedTuple, breaking
our configuration tool.
Code is now updated accordingly and the setup script ensure we're
using the correct version for fido2 package.

* Make Yapf happy

* Fix missing update for fido2 0.9.1

Also split the comment into 2 lines so that the touch is not hidden
at the end of the screen.
