This is the first `cargo test` which uses a linux kernel binary in
testing crosvm's major functionality. To get that binary, the test tries
various sources which may be influenced by the enviroment. If need be,
the chromiumos kernel is downloaded via git, configured, and built so
that crosvm can use it. The resulting binary is cached so that other
tests which need it can run much quicker.
