Update v-list-sys-services

Inspired by Jaap Marcus, I rewrote the check to discover DB System between MySQL and MariaDB.  Now using "mysql -V" to determine existence of each DB variant, subordinate to service type "mysql".  This check looks for the substring "MariaDB" to be contained within the version string (mysql -V) of the currently running database.  Far more foolproof than relying on the existence of a file or folder.

I tested this code on two live HestiaCP installations, one running under MySQL 5.7 and another running under MariaDB 10.5 -- works correctly in both instances.

Hope this helps.
