submanifests: optional: Hotfox for rust trying to build on too many targets

commit c94328f3671a671ac215885c6986b0359a6a37b8
    Author: David Brown <david.brown@linaro.org>

        samples: Properly filter samples by supported Rust targets

A few new samples in the Rust module were added, but missed the proper
filter and platform list, resulting in the daily twister run trying to
build these.
