[libvirt] [PATCH v3 1/4] docs: formatstorage: Update <permissions> docs



- Don't redocument the permissions fields for backingstore, just point to
  the volume docs.
- Clarify that owner/group are inherited from the parent directory at
  volume create/pool build time.
- Clarify that <permissions> fields report runtime values too
