tests: Fix dead_code warning for tuple struct

Browse Source 
```
error: field `0` is never read
  --> futures-executor/tests/local_pool.rs:13:16

   |        |
   |        field in this struct
   |
   = note: `-D dead-code` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(dead_code)]`
help: consider changing the field to be of unit type to suppress this warning while preserving the field numbering, or remove the field
