fixed /etc/mysql/my.cnf creation failure in debian

the config file update depends on the parent directory /etc/mysql being present, which is created as part of the mysql-server package installation. therefore, the mysqld state is split up for debian environments into the package installation and the mysqld configuration. this allows to set the pkg installation as a requirement for the config file management and to set the config file management as a requirement for the mysqld service management
