S390: Change printf format specifier for size_t in heap.cc and spaces.cc

On S390, GCC seems to treat size_t as 'long_unsigned_int'. Which conflicts with the %d format specifier since that expects an 'int'. So changing the macro to PRIuS. This seems to fix the issue while retaining the expected behaviour for all other systems.
