sandbox: Use a prefix for all allocation functions
In order to allow use of both U-Boot's malloc() and the C library's version, set a prefix for the allocation functions so that they can co-exist. This is only done for sandbox. For other archs everything remains the same. Signed-off-by: Simon Glass <sjg@chromium.org>
