Fixed service / framework test suites broken after migration

Bluetooth/service and Bluetooth/framework test suites were
broken after the migration of the files from frameworks.
The Bluetooth/framework test suite is split between stress
tests that require a physical Bluetooth device to run and
the unit tests that test the framework hidden APIs.
Both framework unit tests and service tests are signed
and can be added to the MTS.
