Follow-up fix to MDEV-14952 for Mariabackup

Browse Source 
innodb_init_param(): Initialize btr_ahi_parts=1 for Mariabackup.

btr_search_enabled: Let the adaptive hash index be disabled
in Mariabackup. This would potentially only matter during --export,
and --export performs a table scan, not many index lookups.
