package/python-aiologstash: migrate to flit build backend

We need to add a patch which selects the correct flit build
backend.

As flit is configured as the pep517 build backend for aiologstash
we need to migrate from setuptools to flit prior to migrating
setuptools to pep517 as the frontend will not fall back to using
setuptools once migrated.

+Subject: [PATCH] Fix flit_core build requires/backend.
+
+Only flit_core should be required by pyproject.toml, the regular flit
+package is the pep517 frontend which is not what should be set for the
+build system.
