Yukihiro "Matz" Matsumoto 8e50a45f3e mrb_print_error: handle NULL gracefully to simplify error checking ...

made mrb_print_error() handle NULL by printing "Failed to allocate
mrb_state" when mrb is NULL. since mrb_close() already handles NULL,
this allows simplified error checking pattern:

  if (!MRB_OPEN_SUCCESS(mrb)) {
    mrb_print_error(mrb);  // handles NULL
    mrb_close(mrb);        // handles NULL
    return EXIT_FAILURE;
  }

updated all binary tools (mruby, mirb, mrdb, mrbtest) to use this
simplified pattern, removing nested if checks.
