[PATCH 6/7] Documentation: rust: rename `#[test]`s to "`rusttest` host tests"

[Miguel Ojeda <ojeda@kernel.org>]

Now that `rusttest`s are not really used much, clarify the section of
the documentation that describes them.

In addition, free the section name for the KUnit-based `#[test]`s that
will be added afterwards. To do so, rename the section into `rusttest`
host tests.

 	make LLVM=1 rusttest
 
-This requires the kernel ``.config``. It runs the ``#[test]`` tests on the host
-(currently) and thus is fairly limited in what these tests can test.

+Currently, they are mostly used for testing the ``macros`` crate's examples.
