Fix add_rte_to_flat_rtable() for recent feature additions.
The TABLESAMPLE and row security patches each overlooked this function,
though their errors of omission were opposite: RLS failed to zero out the
securityQuals field, leading to wasteful copying of useless expression
trees in finished plans, while TABLESAMPLE neglected to add a comment
saying that it intentionally *isn't* deleting the tablesample subtree.
There probably should be a similar comment about ctename, too.
Back-patch as appropriate.
