rust: add cargo-c native recipe

This package make it easier to generate C/C++ ABI compatible
header, library and also generate package config file.

It is built around cbindgen (https://github.com/mozilla/cbindgen)
for the header generation, it compiles the library (static or dynamic)
through cargo and finally handle the generation of a custom
package config file.
