error: unexpected cfg condition value: cargo-clippy

[glandium]

Using the msg_send! macro yields warnings like this with upcoming rustc 1.84.0:

error: unexpected `cfg` condition value: `cargo-clippy`

      = note: no expected values for `feature`
      = help: consider adding `cargo-clippy` as a feature in `Cargo.toml`
      = note: see <https://doc.rust-lang.org/nightly/rustc/check-cfg/cargo-specifics.html> for more information about checking conditional configuration
      = note: this error originates in the macro `sel_impl` which comes from the expansion of the macro `msg_send` (in Nightly builds, run with -Z macro-backtrace for more info)

(this is an error in the log because we build with -D warnings)

err, so this was actually fixed in #75, but never made it to crates.io.
