[Kartik Ohri]

vlc | branch: master | Kartik Ohri <kartikohri13 at gmail.com> | Tue Aug 25 15:09:28 2020 +0200| [de0c1fb1c94d8a60142f397e1c6250a2eb142109] | committer: Thomas Guillem

contrib: add cargo

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.
