Fix Switch build (#705)

* Remove duplicate Switch::Init(PostInit) call.

It was called multiple times, causing multiple applet hooks (that all point to the same callback address) to be registered. For some reason, the OS started spamming us with FocusUpdate events via that hook because of that.

* Hide fullscreen and app data directory button on Switch
