Support mdBook preprocessors for TRPL in rustbook

`rust-lang/book` recently added two mdBook preprocessors. Enable
`rustbook` to use those preprocessors for books where they are requested
by the `book.toml` by adding the preprocessors as path dependencies, and
ignoring them where they are not requested, i.e. by all the books other
than TRPL at present.
