Remove some unused dependency declarations

This is based on compiling with `RUSTFLAGS="-W unused_crate_dependencies"` (CC rust-lang/rust#72342) in a recent Nightly (more so than used in the tree as of this writing, CC servo#26661 for work-arounds). Only one crate is actually removed from the dependency graph, others are still dependended from other places.
