libbinder: build on Trusty
Adds a new trusty/ subdirectory containing all the files
needed to build Binder RPC on Trusty, including:
* A RpcServerTrusty class used to create Trusty Binder services
* The underlying RpcTransportTipcTrusty transport that interfaces
between libbinder and TIPC
* Trusty implementations of some OS-specific functionality, like logging
* Make-based build file for libbinder in the Trusty build system
