[Buildroot] [git commit branch/next] package/python-idna: set _SETUP_TYPE = flit

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=8a9da9a8cad5f77902547fab3b24d04175749a7c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Python idna package switched to pyproject.toml in commit:
https://github.com/kjd/idna/commit/2a00e518efe55d2eeb62cd3f88ace7db41338603
which is included in idna v3.4.

When using the old setuptools infra, the package is incorrectly
installed as v0.0, which is then incorrectly detected by other
packages when using setuptools pkg_resources.

The issue can be reproduced with the command:

    python3 <<EOF
    __requires__ = ["idna >= 2.5"]
    import pkg_resources
    EOF

which will fail with output:

    pkg_resources.ContextualVersionConflict: (idna 0.0.0 (/usr/lib/python3.11/site-packages), Requirement.parse('idna>=2.5'), {'hyperlink'})
    pkg_resources.DistributionNotFound: The 'idna>=2.5' distribution was not found and is required by hyperlink

This commit changes _SETUP_TYPE to "flit" to fix this issue.
