datadir must be specified in [mysqld] section of configuration file for mariabackup SST

      Description

      If datadir is not specified in the [mysqld] section of the MariaDB configuration file, then mariabackup SST attempts will fail on the joiner with errors in innobackup.move.log similar to this:

      170530 12:06:47 innobackupex: Starting the move-back operation
       
      IMPORTANT: Please check that the move-back run completes successfully.
                 At the end of a successful move-back run innobackupex
                 prints "completed OK!".
       
      innobackupex based on MariaDB server 10.1.23-MariaDB Linux (x86_64)
      Error: datadir must be specified.
      

      I believe that this behavior was inherited from the xtrabackup-v2 SST method, but it seems a bit unnecessary and it might be fixable. The server obviously knows its own datadir, so can't it specify the value on the command-line or something like that?
