Root Cause and Fix for Galera MySQL 5.7.17 SST Failure Caused by innodb_undo_table_spaces with RSYNC

The Galera MySQL 5.7.17 SST fails when a pre‑initialized node is added because the rsync‑based SST filter omits the independent undo‑log tablespace files (undo*), causing InnoDB to roll back uncommitted transactions; adding an undo* rule to the filter copies the missing files and resolves the error, a fix now upstream.
