tdf#127093 mysqlc: set NO_AUTO_VALUE_ON_ZERO

Without setting this sql_mode, NULL or 0 inserted to an auto-incremented column
of a prepared statement would cause that to be auto generated.

Setting NO_AUTO_VALUE_ON_ZERO allows us to copy/paste auto-incremented
columns which may contain zero values as well.
