kinetis/check-fcfield: skip on IMAGE_OFFSET > 0x410

- fcfield is located in memory at 0x400-0x40f. Its content is only read
  upon reset, therefore if in presence of a bootloader and multiple
  applications, the fcfield will only be read when the bootloader
  is loaded. As long as we flash at IMAGE_OFFSET > 0x410 we do not
  care about the fcfield content since it won't get overwritten.
