Fix namespace collision for test.

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.
