Original issue's description:
> arc: Handle non-launchable apps.
> 
> There are Android apps that can be started indirectly and which
> don't have launchable flag. We had no support such apps in Chrome
> and that caused incorrect behavior in shelf. Fix is to register
> such apps on creation with special flag that prevents them to
> appear in launcher app list and to be pinned in shelf.
> 
> BUG=635536
> BUG=b/30508435
> TEST=Manually on device. Icon of an app (app info) appears on the
>      shelf and cannot be pinned. No app info icon in app list.
