tests: Invoke exit() instead of abort() in case of out of memory

* tests/test_malloc.c (cons, run_one_test): Call exit with a non-zero
code (instead of abort) if out of memory.
* tests/test_stack.c (add_elements): Likewise.
* tests/test_stack.c (main): Use a distinct exit code if a thread
creation failed.
