mariadb-admin flush-status command should do FLUSH GLOBAL STATUS

Details

    Description

      mariadb-admin flush-status runs FLUSH STATUS command. After MDEV-33145, apparently it should run FLUSH GLOBAL STATUS instead, it would be closer to what it did before. I don't believe there is a need for a new command in the tool, as FLUSH [SESSION] STATUS is simply meaningless in this context.
