[bug#27888] [PATCH 05/18] gnu: python-pytest: Add a minimal variant for bootstrapping.

[Marius Bakke <mbakke@fastmail.com>]

* gnu/packages/python.scm (python-pytest-bootstrap, python2-pytest-bootstrap):
New variables.
(python-pytest, python2-pytest): Inherit from bootstrap variants.
(python-six, python-hypothesis, python-pytest-runner,
python-mccabe)[native-inputs]: Use PYTHON-PYTEST-BOOTSTRAP instead of
PYTHON-PYTEST.
