Fix cl-lib package require

[travis]

2.2 isn't actually a version:

cl-lib.el

;;; Change Log:

;; Version 2.02 (30 Jul 93):

To be fair, 0.2 doesn't seem to be a version either, but that's what magit and a host of other packages seem to use.

This fixes an issue where znc can't be installed using package-install-packages.
