all-formats: fix incorrect symlinks i.e. for sd-image formats

Browse Source 
- output $out/$basename instead of $out being a symlink to the resulting file.
  This works around problem where we cannot predict the file extension of the output reliably,
  and therefore the direct symlink had the wrong extension in some cases.
- fix wrong file symlinked under $out for sd image formats
