factory_install: Assume device in factory mode if cr50 version is 0.0.*.
When the device is booted into factory shim right after manufactured,
it is in factory mode but its cr50 is in a default old version and does
not support '-I' option and factory mode. In this case, treat it as
factory mode enabled to avoid turning on factory mode.
