rerun-sdk: ignore test_chunk_index.py (missing datafusion riscv64 wheel)

0.38.x's new tests/integration/test_chunk_index.py imports the datafusion
Python package at module scope, which has no riscv64 wheel anywhere (same
class of gap as test_datafusion_utils.py and test_server.py, already
ignored above). Ignore it in CIBW_TEST_COMMAND the same way, fixing 0.38.0
and 0.38.1 (same test suite).
