MDEV-34713 Backup and restore mariadb_upgrade_info file

Browse source 
The mariadb_upgrade_info file was not being backed up during
mariadb-backup --backup, causing MariaDB to incorrectly prompt for
upgrade after restore.

Add mariadb_upgrade_info to the list of files backed up from the datadir
during backup operations, ensuring the upgrade state is preserved across
backup and restore cycles.
