Allow a foreign table CHECK constraint to be initially NOT VALID.

For a table, the constraint can be considered validated immediately,because the table must be empty. But for a foreign table this isnot necessarily the case.Fixes a bug in commitf27a6b1.Amit Langote, with some changes by me.Discussion:http://postgr.es/m/d2b7419f-4a71-cf86-cc99-bfd0f359a1ea@lab.ntt.co.jp
