mariadb: redefine log-error item

The log-error item which defined in my.cnf is "/var/log/mysqld.err"
previouly and it's not consistent with which created in install_db
service file which will call mysql-systemd-start to create the file
"/var/log/mysqld.log".

And it fails when boot with sysvinit as below:
 $ service mysqld start
 Starting MariaDB.210727 04:05:03 mysqld_safe Logging to '/var/log/mysqld.err'.
 210727 04:05:03 mysqld_safe Starting mariadbd daemon with databases from /var/lib/mysql
 /usr/bin/mysqld_safe_helper: Can't create/write to file '/var/log/mysqld.err' (Errcode: 13 "Permission denied")

So make the log-error item consistent to fix the above failure
and also remove the related workaround when boot with systemd.
