Don't process the download report if no entry was written in the log file

If the download.int_unsort file doesn't exist, the sort command fails and sarg
abort the process.

With this patch, it simply continues the processing optionaly printing an
information message.

Now, it is an error if the sorted file doesn't exists. In previous versions, it
was just a warning.
