Lets not do this way.

It's better to have one function in a cross-platform file:

AppListService* GetAppListService();

There's not necessarily a 1:1 mapping from a platform to a service. On windows
with aura/ash, we need to provide two -- one "win" and one "ash" service, so
they must have different names.
