Find hal_foo_hwservice -> you are hal_foo_client.
Before, it was possible to access a hwservice without declaring
that you were a client.
This introduces the following macro:
hal_attribute_hwservice_client(hal_foo, hal_foo_hwservice)
which makes sure the above implication holds using a neverallow rule.
