feed: use hashlib.sha1 for fallback IDs in Feed._get_entry_id

This fixes what I broke in

    Cleanup global module configuration.

  ...
  -hash = hashlib.md5
  ...

I've come back with sha1 instead of md5, mostly because that's what
Git uses ;).  We don't migrate recorded IDs from the old configuration
method, so the change from md5 to sha1 shouldn't affect anyone.
