[bug#38742] [PATCH] gnu: python-fonttools: Update to 4.2.2

[Riku Viitanen via Guix-patches via <guix-patches@gnu.org>]

This updates python-fonttools to the newest version (4.2.2).
python2-fonttools is only updated to 3.44.0, as the 4.x versions don't support Python 2.

* gnu/packages/python-xyz.scm (python-fonttools): Update to 4.2.2.
* gnu/packages/python-xyz.scm (python2-fonttools): Update to 3.44.0.
