Clone original background declaration

[niksy]

From PostCSS API docs:

If you create a node manually (e.g., with postcss.decl()), that node will not have a source property and will be absent from the source map. For this reason, the plugin developer should consider cloning nodes to create new ones (in which case the new node’s source will reference the original, cloned node) or setting the source property manually.

If there is no original source input file information, plugins like postcss-copy can’t copy file to new location and update declarations.

This has also benefit of referencing original declaration location in source file when you inspect retina images.

Thanks @niksy, a good catch

@simonsmith no problem! Any chance of having this fix pushed as new release? I’m currently using dedicated fork branch for this.

Yes, I'll do it very shortly
