The current implementation of `rust-coreutils` isn't complete yet, and
some of the executables need improvements in order to be able to build a
base Apertis system.

This commit adds the necessary patches to ensure we can use to package
to build Apertis images.

The `revert-twox-hash.dif` patch is no longer needed as a similar change
was merged upstream, which is included in this package as part of the
`sort` backport.

`bump-thread-local` is an empty file causing issues when using `gbp pq`,
and can be safely removed.

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.
