IMPALA-4408: Omit null bytes for Kudu scans with no nullable slots. Kudu does not allocate null bytes if all projected columns are non-nullable. Otherwise, Kudu allocates a null bit for all columns, even the non-nullable ones. The bug was that Impala's memory layout did not match the first requirement.
