[bug] file_check_upload allows empty uploads

Project:      Drupal
Version:      cvs

file_check_upload returns successfully when an empty file is uploaded.
this causes an error in getimagesize() (for example in profile.module's
avatar code). to reproduce: using profile module with avatars enabled,
enter 'xx' in the file upload box and submit the form. the getimagesize
error will be reported since it can't process the file.

the attached one-liner just checks to see that the uploaded file is in
fact non empty.
