Strip release *nix binaries

Might be not needed if built with Rust [1.77](https://blog.rust-lang.org/2024/03/21/Rust-1.77.0.html#enable-strip-in-release-profiles-by-default)+

```sh
wget https://github.com/sstadick/crabz/releases/download/v0.10.0/crabz-linux-amd64 \
    -O /tmp/crabz

ls -l /tmp/crabz  # 7+ MiB

strip --strip-all /tmp/crabz

ls -l /tmp/crabz  # 3- MiB
```
