MDEV-19200: shutdown timeout on innodb.undo_truncate_recover
Optimize the test by dropping the table early and by using only one undo log thread, so that purge will be doing more useful work and less busy work of suspending and resuming the worker threads. The test used to cause shutdown timeout on 10.4 on buildbot, and for me locally when using --mysqld=--innodb-sync-debug. With these tweaks, it passes for me with --mysqld=--innodb-sync-debug.
