Eliminate pg_rewrite.ev_attr column and related dead code.

Browse Source 
Commit 95ef6a3448 removed the
ability to create rules on an individual column as of 7.3, but
left some residual code which has since been useless.  This cleans
up that dead code without any change in behavior other than
dropping the useless column from the catalog.
