Follow up on https://github.com/servo/servo/pull/19515

Selecting over multiple channels in `std::sync::mpsc` is not stable and likely never will be:

https://github.com/rust-lang/rust/issues/27800#issuecomment-260136777

crossbeam-channel is designed specifically to replace `std::sync::mpsc` and fix many of its shortcomings:

This is to be landed together with https://github.com/servo/ipc-channel/pull/183.
