[Buildroot] [git commit branch/next] support/testing/tests/package/test_python_sdbus_networkmanager: use more recent toolchain

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=91e51e267906f41cad530b93879ff3c157f3200d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Since the bump of NetworkManager to 1.50.0 in Buildroot commit
489d1f924979f7a94008e887393702e3c3663705, the
tests.package.test_python_sdbus_networkmanager.TestPythonPy3SdbusNetworkmanager
is failing to build as NM >= 1.50.0 needs headers >= 4.20.

We fix this test by using a newer toolchain. This means we can't use
anymore the basic toolchain config, so we use a fully specific
defconfig for this test.

Fixes:
