Subject: [PATCH] Set RUST_BACKTRACE=1 on AppVeyor (#650)

## Motivation

Currently, the `RUST_BACKTRACE` environment variable is set to `1` on
Travis CI builds:
https://github.com/tokio-rs/tokio/blob/0ca973a7ebc5b8a29beac1ccb6c73ef26ddcbf22/.travis.yml#L49
However, it's not set on AppVeyor. This can make debugging
Windows-specific CI failures challenging for developers on other
operating systems.

## Solution

This branch sets `RUST_BACKTRACE=1` on AppVeyor.
