core/heap.disabled: rip out HEAP_DEBUG code

There's little point in basically just reporting the equivalent of
malloc()/free() each time it happens; there isn't really anything to
debug here.

This also fixes a bug introduced in 101e46d; the HEAP_DEBUG code had
not been properly adjusted and still referenced a variable removed in
that commit, thus breaking compilation with HEAP_DEBUG enabled.
