amcheck: Fix snapshot usage in bt_index_parent_check We were using SnapshotAny to do some index checks, but that's wrong and causes spurious errors when used on indexes created by CREATE INDEX CONCURRENTLY. Fix it to use an MVCC snapshot, and add a test for it.
This problem came in with commit 5ae2087202af, which introduced uniqueness check. Backpatch to 17.
