Nicholas Nethercote 867da30cc7 Avoid kw::Empty when dealing with rustc_allowed_through_unstable_modules. ...

The existing code produces `Some(kw::Empty)` for these invalid forms:

- a non-name-value, e.g. `#[rustc_allowed_through_unstable_modules]`

- a non-string arg, e.g. `#[rustc_allowed_through_unstable_modules = 3]`

The new code avoids the `kw::Empty` and is a little shorter. It will
produce `None` in those cases, which means E0789 won't be produced if
the `stable` attribute is missing for these invalid forms. This doesn't
matter, because these invalid forms will trigger an "malformed
`rustc_allowed_through_unstable_modules` attribute" anyway.
