Rollup merge of rust-lang#41843 - cuviper:oxidized-installer, r=alexcrichton

Update to the Rusty rust-installer

This updates the rust-installer submodule to the new version written in Rust (rust-lang/rust-installer#62), now moved to `src/tools/rust-installer` and invoked in `dist.rs` as a cargo-based tool command.  All of the former shell-script invocations now invoke the tool, otherwise keeping the same arguments as before.

As a small bonus, `rustc-src` now also uses the same tarball generator, so it gains a smaller `.tar.xz` too.

Fixes rust-lang#41569.  r? @alexcrichton
