gnu: python-testresources: Update to 2.0.2.

* gnu/packages/check.scm (python-testresources): Update to 2.0.2. Don't
inherit from python-testresources-bootstrap as it's no longer required
and migrate missing fields from it.
[build-system]: Switch to pyproject-build-system.
[arguments] <test-backend>: Use custom.
<test-flags>: Provide options to run tests with testtools.
[native-inputs]: Add python-setuptools.
[home-page]: Fix it, taken from PyPI <https://pypi.org/project/testresources/>
