- Include binary wsrep_sst_rsync_wan previously omitted.
- Don't build the embedded server. This saves a lot of time and
  around 500 MB of disk space.
- Clean away unused override_dh_installcron. The package does not
  have any *.cron files, so this section is not needed.
- Make mariadb-server run time depend on procps so pgrep works.
  The command pgrep is used in the maintainer scripts of mariadb-server,
  thus we should ensure it is found on the system.
- Include build plugin func_test.so in test package. Don't include yet
  type_test.so since it fails (MDEV-22243).
- Clean away obsolete Lintian overrides.
