Upgrade MariaDB clients with --catalog

The 'mariadb' client has already support for --catalog

We should add the --catalog option to all other MariaDB tools using the
mysql_optionsv(mysql, MARIADB_OPT_CATALOG, catalog);
call
(Note that mysql.cc has code to work with client libraries that does not support the
MARIADB_OPT_CATALOG call. This is there only for developers wanting to know how to
use catalogs with older client libraries and should not be copied to our other clients).

Clients to be upgrade:

• mariadb-admin
• mariadb-show
• mariadb-binlog
• mariadb-dump
• mariadb-slap
• mariadb-check
• mariadb-import
• mariadb-test
• mariadb-conv
• mariadb-plugin
• mariadb-upgrade
• Needs to be run for all catalogs
• We also need to change 'mysql_fix_privilege_tables' to only fix the
  tables that should exists in the catalog:
• 'def' has all tables
• all-other, only the catalog specific tables.
