Originally, vboot1 code used VbExMalloc() and VbExFree() since it needed to talk to EFI firmware that didn't have standard malloc() and free(). Now, coreboot and depthcharge implement them as wrappers around those standard calls. vboot2 code already calls them directly, so let vboot1 code do that too.
