update_engine: Remove ec_version and fw_version

It seems like these values were set for devices like parrot that have
been AUE'ed long time ago. The server side doesn't use this values and
it doesn't seem we need them anywhere. So its better to not send them
anymore since currently we're just sending empty values for them.
