pyx.build: Fix tests with recent setuptools

With setuptools 65 running test_pyx_build_cmdclass is failing because besides
cmdclass_custom.py it sees nearby golang_pyx_user/ and golang_dso_user/ with
top-project setups and rejects it:

    ---- 8< ----
    golang/pyx/build_test.py::test_pyx_build_cmdclass error: Multiple top-level packages discovered in a flat-layout: ['golang_pyx_user', 'golang_dso_user'].

    To avoid accidental inclusion of unwanted files or directories,
    setuptools will not proceed with this build.

    If you are trying to create a single distribution with multiple packages
    on purpose, you should not rely on automatic discovery.
    Instead, consider the following options:

    1. set up custom discovery (`find` directive with `include` or `exclude`)
    2. use a `src-layout`
    3. explicitly set `py_modules` or `packages` with a list of names

    To find more information, look for "package discovery" on setuptools docs.
