sandbox: Implement the bootm command for sandbox
When sandbox does a 'bootm' to run a kernel we cannot actually execute it. So just exit sandbox, which is essentially what U-Boot does on other archs. Also, allow sandbox to use bootm on any kernel, so that it can be used to test booting of kernels from any architecture.
