Change syntax of new CHECK NO INHERIT constraints

Browse Source 
The initially implemented syntax, "CHECK NO INHERIT (expr)" was not
deemed very good, so switch to "CHECK (expr) NO INHERIT" instead.  This
way it looks similar to SQL-standards compliant constraint attribute.

Backport to 9.2 where the new syntax and feature was introduced.

Per discussion.
