[Buildroot] [Patch v7 10/10] cargo: new package

This new package provides Cargo, the Rust official package manager.
Cargo is written in Rust and uses Cargo as its build system. It also
depends on other Rust packages.
Normally, a previously installed version of Cargo would be used to:
1. Fetch the dependencies.
2. Build the new version of Cargo, using the available Rust compiler.
But the fetching step prevents offline builds. So instead two features
of Cargo are levelled: vendoring [1] and local registry.
First, a tarball of the build dependencies generated using `cargo
vendor` is fetched along with Cargo source code.
Then, the build process is as follows:
1. The tarball of the build dependencies is uncompressed in a local
registry.
2. A snapshot of Cargo, provided by cargo-bootstrap, builds the final
version of Cargo.
3. A configuration file telling Cargo how to cross-compile programs for
the target is generated and installed.
Currently, only the host variant is provided.
