test_build.sh: Add build_rust

Add a function to check the rust projects. cargo test, fmt, and clippy
are run to check unit tests, code format, and lint. The rust packages
are built against the just compiled 'all' variant of libflashrom. cargo
is run offline so that jenkins works. The tests are only run if cargo
is installed.
