Make AIDL HAL client attribute an exclusive client.

Like HIDL HALs, if we have a service which is allowed to access
hal_<foo>_service, we want that service to have the attribute
hal_<foo>_client.

Unlike HIDL HALs, some AIDL services are allowed to get ahold of all
HALs, so these have to be exempted from this check.
