Don't print crates.io-index URL when Updating

Following the lead from PackageId's Display, only display the registry's
URL if it's not the default registry (aka crates.io).

Before:

    $ cargo install lazy_static
        Updating registry `https://github.com/rust-lang/crates.io-index`

After:

    $ dcargo install lazy_static
        Updating registry
