BUG#21879694 - /VAR/LOG/MYSQLD.LOG HAS INCORRECT PERMISSIONS AFTER INSTALLING SERVER FROM REPO

Description:
This issue doesn't effect any default installation of repo rpms if user uses
init scripts that are shipped as part of package but will have trouble if
user tries to createdb or start server manually.

After installing mysql-server from repository(yum,zypper) /var/log/mysqld.log
is created with logged in user and group permissions instead of with mysql
user and group permissions,due to which while creating database or starting
server, it is failing

Fix:

Updated the user and group permissions of the /var/log/mysqld.log and
/var/log/mysql/mysqld.log (for sles) files to mysql.
