StdLib/LibC/StdLib/Malloc.c: Revert cast removal to fix GCC build breakage.
 
The cast to (void**) is needed for the last parameter of the AllocatePool call in malloc().  This is because type CPOOL_HEAD** is not automatically promoted to void**, as required by AllocatePool().
 
This was originally addressed in SVN revision 15474 but removed again in 15664.
