qsql_oci: fix option types

These are signed values. Notice the initialization to -1, which
apparently never worked. The unsigned types previously used may
be due to confusion with other arguments of OCIAttrSet():

sword OCIAttrSet ( dvoid       *trgthndlp,
                   ub4         trghndltyp,
                   dvoid       *attributep,
                   ub4         size,
                   ub4         attrtype,
                   OCIError    *errhp );

Examples found in web searches also use signed int.
