[sr-dev] [kamailio/kamailio] db_unixodbc: MariaDB partition is a reserved word and not quoted (Issue #3742)

### Description partition is now a reserved word in MariaDB 10. the column name is correctly quoted with native libmysqlclient/libmariadb so works

the column name is not quoted with unixodbc+(libmyodbc8|libmaodbc) and so fails

### Troubleshooting try unquoted insert

-- fails unixodbc+libmaodbc insert into location (partition) values (1000);

-- works native libmysqlclient|libmariadb insert into location (`partition`) values (1000);

#### Reproduction 1. config enable usrloc / registrar with unixodbc + MySQL/MariaDB connector

#### Debugging Data

SQL insert into statement fails
