Refactor the ArgIterator interface

They now follow the interface provided by the standard library. This now
means that we no longer needs `args.OsIterator` as that the one from
`std` can now be used directly.

Also remove `args.ShellIterator` as a simular iterator exists in `std`
called `ArgIteratorGeneral`.
