To avoid linking issues with Rust's libtest, the crate for the test utility was changed to 'uutest'. However, the user doesn't need to see this so a few hoops were jumped through to make this transparent. I also updated the make rules to build the individual features first and then uutils. This makes 'make && make test' look more organized.
