update rayon, rayon-core, which drops it's deps on num_cpus and crossbeam-channel (for bootstrap too) (https://github.com/rayon-rs/rayon/blob/v1.8.0/RELEASES.md)
update erro, which drops errno-dragonfly (https://github.com/lambda-fairy/rust-errno/blob/5341791935df601306ffc57a665763c4ecd72755/CHANGELOG.md)
