[CBRD-25358] error handling when using for update clause for system tables such as db_root, dual, etc.

[beyondykk9]

http://jira.cubrid.org/browse/CBRD-25358

No errors occur when using the "for update" clause for system tables such as db_root and dual. Semantic error handling is required.

select /*+ recompile */ * from db_root for update;

expected result: ERROR: update is not autorized on db_root.
