Fix handling of filenames of linked images in .odg export

- export of .odg files was completely broken on Windows as
  "documentUri = Inkscape::URI(filename);" always failed
  (Windows paths are never valid URIs because of '\')
- Linked images did not seem to be working on any OS
  (probably regression in 6f844ef457690c841b0be91d70b1e54b61c04812)

I assume support for linked images is still sketchy but seems to
work in the most common cases; support for embedded images seems
to be non-existent, though.
