package/cargo-bin: remove and use cargo-bin from rust-bin package

Rust upstream distributes tarballs with separate rust and cargo
binaries, but also tarballs with everything together. The latter
contains a bit more than what we need, so the download is slightly
larger than separate cargo-bin and rust-bin. But it simplifies our life
if we do the same in rust-bin as in rust (i.e. get both rust and cargo).
