upgrade MySQL system tables

   This script updates all the mysql privilege tables to be usable by
the current version of MySQL

Got a failure from command:
cat /usr/share/mysql/mysql_fix_privilege_tables.sql | /usr/bin/mysql --no-defaults --force --user=root --host=localhost --database=mysql
Please check the above output and try again.

Running the script with the --verbose option may give you some information
of what went wrong.

If you get an 'Access denied' error, you should run this script again and
give the MySQL root user password as an argument with the --password= option
