aiokafka: add build-aiokafka.yml for riscv64 wheels (#858)

* **Package**: `aiokafka`
* **Version**: `0.14.0`
* **Source**: https://github.com/aio-libs/aiokafka
* **Docs**: http://aiokafka.readthedocs.org

Compiles the Cython `_crecords` extension (Kafka record batch encode/decode); the rest of the asyncio Kafka client is pure Python. Upstream publishes no riscv64 wheel.

Mirrors the `package-wheel` job of [upstream's `publish.yml`](https://github.com/aio-libs/aiokafka/blob/v0.14.0/.github/workflows/publish.yml).

**Differs from upstream**
- Test dep versions pinned to `requirements-ci.txt` - newer pytest fails `test_requests.py` under this project's `filterwarnings = ["error"]`.
- `gssapi` dropped from test deps - needs krb5 headers and is only reached by the docker-backed SASL tests, which are skipped anyway (see Testing).

**Testing**
- No `--docker-image`, same as upstream's own wheel-test jobs (none run a Kafka broker either); tests needing one skip via upstream's own `kafka_image` fixture.
- `CIBW_TEST_SOURCES` stages `tests` + `pyproject.toml` so the repo-root `aiokafka/` can't shadow the installed wheel; upstream's own CI does the equivalent by `rm -rf aiokafka` before testing.
- `cramjam` (snappy/lz4/zstd codec backend) is on the registry for riscv64, so those tests run instead of being skipped.

**License**: OK

Built on cp312; 749 passed, 332 skipped.
