[CI] use pytest.ini to manage vllm native tests (#5)

### What this PR does / why we need it?
Use `pytest.ini` to manage vllm native tests.
This will convert the original test script whitelist to a blacklist to
prevent missing the newly added test scripts of the upstream vLLM.

**note**: _we do **not** manage the test scripts of vLLM-Ascend in
`pytest.ini`, because if we do so, there will be conflicts between vLLM
and vLLM-Ascend's `conftest.py`._
### Does this PR introduce _any_ user-facing change?
N/A

### How was this patch tested?
CI passed with new existing test.
