[PATCH v2 12/32] sandbox: Use a prefix for all allocation functions

[Simon Glass]

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.
