sfeed_update: improve consistency of feed creation and merging

- Improve feed creation with empty results and new feed files.
  Always make sure the file is created even when it is new and there are also no
  items (after filtering).

- Consistency: always use the same feed file for merging.
  Do not use "/dev/null" when it is a new file. This works using sort, but is
  ugly when the merge() function is overridden and does something else. It should
  be the feed file always.
