Release rust-coreutils version 0.0.12-0+apertis6.v2023.1

Rust binaries stripped at linking time are smaller than binaries stripped with dh_strip. Since we want the smaller binary possible for rust-coreutils, we strip debug symbols at linking time, but that means dh_setup_copyright is then not able to extract required data. As a workaround we build here a non-stripped binary only for dh_setup_copyright.
