syslinux.bbclass: Fix default serial port string
The default value of SYSLINUX_SERIAL_TTY is not correct.
It should be console=ttyS0,115200 else the boot string generated in
the syslinux menus for the serial choice is not correct. The kernel
boot parameters will get set to:
/vmlinuz initrd=/initrd LABEL=boot root=/dev/ram0 ttyS0,115200
Note that the above is missing the "console="
The default value will now work the same as the value found in
grub-efi.bbclass.
