edition: Update absolute paths to 2018 style

This is an easy step toward adopting 2018 edition eventually, and will
make any future CL that sets `edition = "2018"` this much smaller.

The module system changes in Rust 2018 are described here:

https://doc.rust-lang.org/edition-guide/rust-2018/module-system/path-clarity.html

Generated by running:

    cargo fix --edition --all

in each workspace, followed by bin/fmt.

TEST=cargo check
TEST=cargo check --all-features
TEST=cargo check --target aarch64-unknown-linux-gnu
