[OpenBIOS] [PATCH 7/7] ppc: move fake copyright hooks from adler32 word

[Mark Cave-Ayland]

Instead insert the fake copyright just before we call the client with
go and remove it before control is returned back to the interpreter.

This effectively hides the notice from everyone except for bootloaders.
