payloads/external/SeaBIOS: Update makefile for olddefconfig

Instead of creating the SeaBIOS .config file for QEMU, then changing
    things to be coreboot specific, create a default config for coreboot,
    then run olddefconfig to use the SeaBIOS defaults as they're set for
    coreboot.  This leads to a cleaner config.

Note that CONFIG_THREAD_OPTIONROMS defaults to enabled for SeaBIOS if
    we're building for coreboot, so I reversed the logic.

I *ASSUMED* that leaving CONFIG_QEMU_HARDWARE=y and CONFIG_DEBUG_IO=y
    previously was an oversight.  If this is not correct, please let me
    know and I'll add them it back in.  SeaBIOS disables these by default
    if building for coreboot.
