audiohal: Always load A2DP module locally
This makes legitimate unix socket interaction between A2DP
module and the Bluetooth stack.
Implemented by allowing both "local" and "hidl" interface
wrappers to co-exist for devices and streams. A "hybrid" device
factory is introduced to create an appropriate implementation
of a device depending on the requested module name.
