sandbox: Use malloc() and free() from os layer

Browse Source 
At present sandbox calls malloc() from various places in the OS layer and
this results in calls to U-Boot's malloc() implementation. It is better to
use the on in the OS layer, since it does not mix allocations with the
main U-Boot code.

Fix this by replacing calls with malloc() to os_malloc(), etc.
