Filter returned entries and add "binder_" package prerix

Reporting all the Binder services that exist in the device resulted in
excessive growth of the data to handle.

Reduce the data size by introducing a Set that keeps the list if
services being monitored. Every service in the Set is reported
regardless of its availability. For this reason, the new `is_available`
field is also introduced and `interface_descriptor` is reported as an
empty string if the service does not exist.
