Subject: VTU: put xml closing element on separate line
X-Git-Tag: v9.4.0-rc1~531^2~1

VTU: put xml closing element on separate line

We try to output VTU XML data in somewhat pretty way like
  <Points>
    <DataArray type="Float32" NumberOfComponents="3" format="binary">
[BASE64 data]
    </DataArray>
  </Points>
but we were missing a newline after writing scalar base64 data. Fix
this.
