Intercept qmldir files with the url interceptor

There's another code path which loads qmldir files directly, and it did
not use the interceptor when available.

Note that this, like other interceptors, does not affect baseUrl and so
any other qmldir file still must have paths relative from the initial URL.

+This qmldir file is intentionally invalid, as the URL interception should prevent it being accessed.
