Run `rustfmt` on `kernel`, `libredox` and `liborbital`

Created by: polymetric1

Note: I used a cutting edge debug version of rustfmt, so if anyone sees any problems, say something immediately, don't hesitate, even if you don't think it's a problem. I did build, run and test this though, and the only functional problems this could introduce would be rejected by the compiler, so I think it worked fine.
