[SeaBIOS] coreboot's memtest86+ is buggy compared to memtest86+ floppy

coreboot's memtest86+ payload is buggy compared to memtest86+ floppy (which could be downloaded from memtest.org and added to CBFS to be accessible as SeaBIOS menu entry). at AMD Lenovo G505S and maybe some other coreboot laptops, the USB devices like keyboard are not working at coreboot's memtest8
