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 5ae2087202, which introduced
uniqueness check.  Backpatch to 17.
