Remove Freed Object Tracker.

The root cause of the Android "core trampler" has been found.  This
reverts the tracker used to record what objects were previously
allocated in the memory block used by the object being overwritten.

While the general "freed_object_tracker" module is generic and could
be re-used should similar tramplers appear, it is best not to leave
code in the build that is not actually being used.  Feel free to
ressurect this code in the future if there is a need for it.
