futility: cmd_update: Access system firmware using external flashrom
To manipulate the firmware contents on device, we need to access the
flash chipset (usually via SPI) on system. The `host_flashrom` provides
a way to call external program "flashrom" for reading and writing
firmware. So the `update_firmware` can now load "system current
firmware" using flashrom.
Note in the future we may want to statically link the flashrom as
library so there won't be external dependency.
