python-zope-event: fix build with setuptools >= 81

The pyproject.toml for zope.event 6.1 specifies a strict build
dependency of setuptools>=78.1.1,<81. We currently package
setuptools>=81, causing pip to report a missing dependency and
fail the build.

Add patch 001-relax-setuptools-version.patch to drop the <81 upper
bound, allowing the package to build with any recent setuptools.

Add test.sh to verify the installed version and exercise the core
event API (subscribers list, notify(), event dispatch).
