rec: Use the correct RPZ policy name when loading via XFR

This commit fixes two issues:
- if the existing zone name is not empty we should use it, instead of
  the zone domain
- if the zone domain has to be used, it should not include a final dot

(cherry picked from commit 3e86a970828dda814a140c9613311a8507c3c458)
