ft_ubertest: Fix seg fault

Fix crash in uber test:

#0  0x00000000004036fb in fts_cur_info (series=<value optimized out>,
    info=0x60c920) at complex/ft_config.c:613
#1  0x0000000000402568 in ft_fw_client (argc=<value optimized out>,
    argv=<value optimized out>) at complex/ft_main.c:412
#2  main (argc=<value optimized out>, argv=<value optimized out>)
    at complex/ft_main.c:511

The opts strings may be overrun.

Set the default destination port, so that the test can run.
