[PATHCH,V3,2/4] classes-recipe: add cargo_c.bbclass

From: Frederic Martinsons <frederic.martinsons@gmail.com>

This class can be used inside rust recipe to generate
a rust library that can be called by C/C++ code.

The rust recipe which uses this class has to only replace
"inherit cargo" by "inherit cargo-c".

Typo: cargo-c -> cargo_c

Shouldn't that be "${prefix}" rather than "/usr"?

Yes you're right. I'll send a v4 with that correction and fix the typo you
mentioned. Thanks.
