toolchain: Add rust-toolchain file The rust-toolchain file defines a local toolchain override that is respected by rustup when running Cargo commands. This override applies to the directory containing the rust-toolchain file as well as its subdirectories. It makes it so that running `cargo check` or `cargo fmt` always uses the intended toolchain, unless overridden by e.g. `cargo +nightly check`, regardless of what toolchain the user has selected as global default. No more accidentally running a too new or old version of rustfmt! We will need to bump this version number when rolling to a newer toolchain in ebuild. When that happens, local Cargo commands by other crosvm developers will automatically download the new toolchain. For details on rust-toolchain: https://github.com/rust-lang-nursery/rustup.rs#the-toolchain-file https://github.com/rust-lang-nursery/rustup.rs#override-precedence This file is ignored during emerge. Verified by setting rust-toolchain to a bogus version number and emerge succeeded anyway.
