[vlc-devel] [PATCHv3 4/7] contrib: add cargo

[Thomas Guillem]

From: Kartik Ohri <kartikohri13 at gmail.com>

This will install rustup, cargo, and cargo-c into contrib/bin/.cargo
This installation will be used by default for all rust contrib builds.

The correct cargo target will be automatically installed when needed.
