lib/malloc: Implement a simple free() only for last malloc()
Implement a free() that supports only the last malloc(). Rewind
the heap to the last allocation point if the ptr to be freed is
matching the end of heap before last malloc(). With current situation,
since free() is no-op, every call to malloc() is a memory leak.
BUG=b:140124451
TEST=Wrote a test function to do malloc and free operations.
