Deb: Format files with debputy reformat --style black

This formats and sorts the files the same way they are in the official
Debian packaging, making it easier to compare the files in Debian vs
upstream using commands such as `git difftool --dir-diff main --
debian`. Comparing the contents at least once a year is important in
ensuring all packaging improvements get their way into both Debian
official and upstream Debian packaging.

The formatting done by `debputy reformat --style black` is basically the
same as running `wrap-and-sort -vast`.

There are no functional changes, this is a pure formatting change.

This is intentionally done on the `main` branch in MariaDB. The stable
release branches are unlikely to ever get any changes in the
`debian/control` file, and thus formatting or maintaining it is
irrelevant. The merges from stable releases to latest `main` should not
bring any `debian/control` file changes, as adding or removing
dependencies, changing Debian compat levels or other changes are
invasive and shouldn't be done in stable releases at all.
