bash-completion: update to 2.12.0.
Two backported patches from upstream (i.e. [#688](https://github.com/scop/bash-completion/pull/688) and [#675](https://github.com/scop/bash-completion/pull/675)) are deleted since the new version includes them already.

#### Testing the changes
- I tested the changes in this PR: **briefly**

This PR FAILS to build on x86_64-musl with the following warnings:

```sh

```

How can I solve the error `/etc/bash_completion.d is forbidden. Use /usr/share/bash-completion/completions.`? I searched a bit but could not find something useful.
