    scripts/runqemu: Add always ttyS1 when no serial options are specified
    
    We always wants ttyS0 and ttyS1 in qemu machines (see SERIAL_CONSOLES),
    if not serial or serialtcp options was specified only ttyS0 is created
    and sysvinit shows an error trying to enable ttyS1:
    
         INIT: Id "S1" respawning too fast: disabled for 5 minutes
    
    [YOCTO #10491]
