Title: Download Rust snapshots in make rather than configure.

When parallel make (`-j`) is used, this enables building non-Rust dependencies while the Rust compiler is being downloaded.

On my laptop, from an empty build directory, `~/projects/servo/configure --disable-optimize && make -j6` goes from ~7 minutes to ~6 minutes. The difference matches the download time.
