selfboot: fix bug in valid_area()

valid_area will accept a region as valid for the payload if only a part
    of coreboot fits in that region. This means if a payload reaches into a
    neighboring RESERVED region, coreboot would not care and happily
    overwrite that region, as long as the payload also writes to some RAM.
