um: Remove the redundant declaration of high_physmem

Browse source 
high_physmem has already been declared in as-layout.h, so there is
no need to declare it explicitly in the .c file again.

While at it, group the declarations of __real_malloc and __real_free
together to make the code slightly more readable.
