Fix the logrotate file
    
    The sources contains two versions of the logrotate file:
    * mysql-8.0.30/support-files/mysql-log-rotate.in
    * mysql-8.0.30/packaging/rpm-common/mysql.logrotate.in
    
    Until now, the first one was used. However logfile location
    specified in that logrotate configuration file was wrong.
    ( /var/lib/mysql/mysqld.log )
    
    From now on, we will use the second one, which is meant to be
    used in RPM packages, and which respects their FSH layout.
    ( /var/log/mysql/mysqld.log )

    As a side-effect, the whole configuration is now commented out.
    So users now need to touch the file before they can start using it.
    
    However once the configuration is un-commented,
    it will work out-of-the-box (unlike until now).
