[bug#50018] [PATCH v2 16/19] gnu: python-celery: Enable tests.

[Vinicius Monego <monego@posteo.net>]

* gnu/packages/python-xyz.scm (python-celery)[arguments]: Remove
'patch-requirements phase. Remove #:tests?. Override 'check phase.
[native-inputs]: Add python-flaky, python-iniconfig, python-moto,
python-msgpack, python-pytest-celery, python-pytest-subtests,
python-pytest-timeout, python-toml.
---
Enabled backend tests and added python-msgpack to native-inputs. Subsequent patches are rebase only.
