Prune unused entries from the 'master' array returned by get_pod_metadata().

The description is only used to generate MANIFEST entries now from 'readmes'
and 'pods'. now that perl.pod is the master and is no longer generated from
pod.lst

The leafname/podname distinction is only used by is_duplicate_pod(), so can
be replaced by simple flag, 'dual'.

Replace the now-unused entries with undef to preserve the indices.
