LP#1374091: Speed up metarecord version of unAPI mra call

The change to metabib.record_attr_flat in the previous commit caused
a regression in the plan used in unapi.mmr_mra.  This commit addresses
that by unrolling the mra view when used in context with metarecords,
which are shaped differently and require slightly different access
patterns.
