Subject: [PATCH] Remove Redundant Trait Bound (#4169)

I realized this is redundant while reasoning about how the `store` is implemented given the [definition of `ItemStore`](https://github.com/sigp/lighthouse/blob/v4.0.1/beacon_node/store/src/lib.rs#L107)
```rust
pub trait ItemStore<E: EthSpec>: KeyValueStore<E> + Sync + Send + Sized + 'static {
    ...
}
```
