Fix rustc-guide toolstate tracking.

The rustc-guide is still not saving its toolstate.  It needs to be done explicitly.

Note: There are some confusing bits here, like without `--no-fail-fast`, it saves the wrong value in `toolstates.json`.  Also, "rustbook" is always added as "test-fail".  Presumably [this code](https://github.com/rust-lang/rust/blame/63c1f17d950bfefc8f356777f124f304f0575c76/src/bootstrap/tool.rs#L201-L205) assumes everything fails until it passes tests, which is a bit confusing for things that don't run tests.
