MDEV-19347: Mariabackup does not honor ignore_db_dirs from server

Browse source 
config.

The solution is to read the system variable value on startup and to fill
databases_exclude_hash.

xb_load_list_string() became non-static and was reformatted. The system
variable value is read and processed in get_mysql_vars(), which was also
reformatted.
