SCI: Give kernel calls a valid stack pointer
Some kernel calls need to be able to call back into game script code, which requires a valid stack pointer for use with invokeSelector. An example of this is the guest additions code that syncs audio volumes from ScummVM: it needs to be able to call into the game scripts responsible for managing the in-game audio volume UI.
