Help in diagnosing the number of old reports to keep

The lastlog and lastlog1 files are stored in the temporary directory
instead of the output directory and they are not deleted when sarg exits
if the users asked not to delete temporary files.

Some debug messages give indication about what is happening with respect
to the old reports deletion.
