Subject: Restore rust-toolchain file.

Removing this file broke Heroku deployments. The emk/rust buildpack
relies on this file to detect the Rust version, and as this code
_requires_ a nightly, the default stable version fails to deploy.

Unfortunately, this effectively leaves the project pinned to a specific
nightly version until and unless one of a few things happens:

* We remove the test step that verifies formatting,
* Travis adds a non-minimal Rust profile,
* We migrate CI to a service that supports a more complete Rust profile,
  or
* Nightly has rustfmt again.

See <https://github.com/emk/heroku-buildpack-rust#specifying-which-version-of-rust-to-use>.

This reverts commit f43bcb502435ccd99e163671204371dd8b62024f.
