odbc: Suppress signedness warnings for 'char *'
Three different pointer types are used for strings. SQLCHAR pointer - used against ODBC driver char pointer - used against erl_interface byte pointer - used internally SQLCHAR is 'unsigned char' while erl_interface is 'signed char' byte pointer should probably not be used at all.
