Fix [ #489673 ] memory leak in test_symtable: Free the st_future slot.

The st_future slot of the symtable is not freed by PySymtable_Free()
because it is shared by the symtable and compiling structs in
compiel.c.  Since it is shared, it is explicitly deallocated when the
compiling struct is freed.
