Subject: [PATCH 1/4] gnu: python-dictdiffer: Fix broken test suite.

From: Giacomo Leidi <[email-masked]>
Date: Wed, 5 Jan 2022 02:24:05 +0100

This patch prevents pytest from running a PEP8 check on the source,
since it breaks pytest's own collection phase.

* gnu/packages/python-xyz.scm (python-dictdiffer)[snippet]: Patch pytest
configuration to prevent PEP8 testing.
