[lookaside_upload_sig] Fix log message to reflect reality
    
    The log message was reporting sha1sum regardless of what actualy shaX
    was used.
    
    Tested by uploading a new src to the lookaside
    
    ```
    ../centos-git-common/lookaside_upload_sig -f createrepo_c-0.20.1.tar.gz -n createrepo_c
