Clark Boylan 902158bb8f Don't treat service as enabled if in disabled list
The old implementation for is_$service_enabled simply checked if any of
the subservices were enabled and if so the service was considered to be
enabled. This makes disabling services complicated as it means you have
to list every single subservice which can and do change over time.

Instead also check if the generic service name is in the disabled
services list and if so don't treat the service as enabled.
