eval_error.c: revert the "reversed" backtrace [Feature #8661]

Now, the order is good, old-fashioned style:

```
$ ./local/bin/ruby -e 'def foo; raise; end
def bar; foo; end
def baz; bar; end
def qux; baz; end
qux
'
-e:1:in `foo': unhandled exception
	from -e:2:in `bar'
	from -e:3:in `baz'
	from -e:4:in `qux'
	from -e:5:in `<main>'
```
