Add simple fake for native service manager.
Reusing the existing binder-based native service manager has
proved problematic in host/test environments.
So as a workaround, this commit creates a IServiceManager native
implementation that can be communicated with directly.
Bug: 147595993
Test: m fakeservicemanager_test; fakeservicemanager_test
