Christian Göttsche 9ca3279507 test: add tests for zero sized realloc(3) 
C23 declared calling realloc(3) with a non-NULL pointer and zero size
Undefined behavior.
Check that hardened_malloc handles that case sanely by free'ing the old
pointer and returning a special pointer, like `malloc(3)` called with
size zero.
