help to fix ftbfs issue #1052815 for python-sparse

[Bo YU <tsu.yubo@gmail.com>]

Hi,

I am looking at the issue and trying to fix it.

If upgrading to 0.14.0[0] directly does not fix the issue and it is in
complicated situation. So below I will explain what I do.

First to fix #1052815[1], wo need to adjust pybuild with custom way:
```
PYBUILD_SYSTEM=custom \
PYBUILD_TEST_ARGS="{interpreter} -m pytest -v" \
```
Okay, it works. But unfortunately, the test cases failed.

```

```

The upstream has reported the bug[2] then I applied the workaround in
issue 8993[3], but it still got some cases failed:
```
=========================== short test summary info ============================

FAILED sparse/tests/test_coo_numba.py::TestBasic::test_repack_attrs - numba.c...
```

It seems the bug was raised by numba and fixed in 0.57 but not sure
why it fails on Debian here.

But maybe I am wrong to get the conclusion above because from upstream
issue 393[4], the problem maybe
due to entry points of sparse. But I have no idea how to fix the issue
properly. For example, If I install
python3-hyperspy[5] to run tests and it will pass. I suspect
python-sparse was installed properly when installing
python3-hyperspy which depend on python-sparse and installing
python3-hyperspy should not to as workaround at all.

So what is properly way to fix the issue? TIA.

BR,
Bo
