test(agent): Drop redundant fixture attrs and case_id column

- Remove unused local_config + _docker mock from the NUMA-locality
  cpu_plugin fixture: CPUPlugin.generate_docker_args doesn't read them.
- Replace the case_id parametrize column with pytest's `ids=` kwarg;
  pytest already labels failures via the parametrize id.
