subscriber: rename trait CollectorExt to CollectExt

The trait being augmented is the 'Collect' trait, so name the trait
that extends it 'CollectExt'.

This is in keeping with the extension trait naming conventions
documented in Rust RFC-445, and also with the spirit of the
discussion in tokio-rs/tracing PR tokio-rs#1015.
