[Impala-ASF-CR] IMPALA-4408: Omit null bytes for Kudu scans with no nullable slots.

Alex Behm has uploaded a new change for review.

Change subject: IMPALA-4408: Omit null bytes for Kudu scans with no nullable slots.

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.
