       sfeed_update/sfeed_opml_export: only allow regular files
       
       Be more strict and only allow regular files. It makes no sense to use device
       files or fifos with sfeed_update and it can cause issues, because sfeed_update
       expects to read the config file for each (child) invocation also.
