The post-installation script of at least one packages makes use of the
`-k` option for `sort`, which isn't implemented in release 0.0.6 of
`rust-coreutils`.

As this has since been implemented upstream, this commit picks the
corresponding patches so we can benefit of those improvements.

rust-coreutils (0.0.6-1~exp1) experimental; urgency=medium
.
  * New upstream release
.
rust-coreutils (0.0.4-1~exp2) experimental; urgency=medium
.
  * Binaries have been moved in usr/lib/cargo/bin/coreutils
    The rational is that some other rust programs are installed
    in this directory (ex: /usr/lib/cargo/bin/fd). So, users might
    add /usr/lib/cargo/bin/ to their PATH and caused some unexpected
    errors if the Rust coreutils binaries aren't behaving like GNU's.
