Fixes problem with lint warnings in different versions of Rust.

- The crate supports several different versions of rust and in some of
  these versions the Clippy lint tool introduces new warnings that are
  not present in previous versions of rust. This causes a warning when
  compiling. This has been fixed in this commit by using the
  `rustversion` crate to only add the lint if the crate is being built
  with a version of Rust that has it.
