tdf#116745 handle <object> element when localizing

The <object> element was brought to Pootle by wrapping it in a
<paragraph> element. However, the localized build helper changed
 < and > to HTML entities, which broke the rendering of the localized
<object> element.

This patch addresses the issue and keep the < and > as is.
