Switch EFT boot1 to use libstand
ARM and i386 already required libstand so switch to using it for all patforms, allowing the removal of custom print and memory methods. This is also a pre-cursor to enabling WARNS which highlighted a number of issues with the removed methods. MFC after: 2 weeks X-MFC-With: r293268 Sponsored by: Multiplay
