Bug #16952: Kernel.exec gives an incorrect error message when passed a scri=
pt with a non-existing shebang

```
$ cat myscript.rb =

#!/bad/ruby/shebang

puts "Hei!"

$ ruby -e 'Kernel.exec("myscript.rb")'

Traceback (most recent call last):
	1: from -e:1:in `<main>'
-e:1:in `exec': No such file or directory - myscript.rb (Errno::ENOENT)
```

From the error, I understand that the script is not there, but the script i=
s clearly there.

I would've expected something more similar to what you get if you try to ru=
n the script directly from the shell:

```
$ ./myscript.rb =

bash: ./myscript.rb: /bad/ruby/shebang: bad interpreter: No such file or di=
rectory
```
