This was required because my initial take on Rust let the build process
download the rust-stage0 bzip2 tarball and uncompress it on its own. As
the bootstrap binary will now be provided by the rust-bootstrap
package, this is not needed anymore.

bz2 tarballs are widespread. So having support for this format in
host-python, regardless of Rust, will benefit the user.
