* Clean up autobake-deb.sh

  - No need to define any TokuDB rules, there is no such package
  - No need to define RocksDB arch, it already has "Architecture:" line
  - No need to dh-systemd backwards compat stanza, neither Debian Jessie
    nor Ubuntu Xenial has any new MariaDB 10.5 releases anymore
  - Minor spelling fixes

* Ensure dch runs non-interactively so builds pass with new dch version

  A recent version of dch (available in Ubuntu Hirsute and Debian Bullseye)
  had a change in behaviour that it started prompting if the DEBEMAIL or
  EMAIL variable as unset, asking for confirmation. We can't have anything
  interactive in our build scripts, so prevent this prompt by giving
  --controlmaint to the command, so it always uses the name and email from
  the debian/control file and does not prompt anything.

  The command-line argument has been around for a long time, so it is safe
  to use on all Debian/Ubuntu builds we have.

  See https://manpages.debian.org/jessie/devscripts/dch.1.en.html

  Since MariaDB 10.5 is the oldest release we still release for Ubuntu Hisute
  and Debian Bullseye, merge this on 10.5 and from there merge up to latest.
  No need to consider 10.2, 10.3 and 10.4 as those will not be released for
  Ubuntu Bullseye or Ubuntu Hirsute.
