efi/libstub: zboot: Avoid eager evaluation of objcopy flags
The Make variable containing the objcopy flags may be constructed from the output of build tools operating on build artifacts, and these may not exist when doing a make clean. So avoid evaluating them eagerly, to prevent spurious build warnings.
