futility: Use crosid to probe firmware manifest key

Use the API function crosid_get_firmware_manifest_key from libcrosid
instead of "mosys platform model" to get the firmware manifest key.

Note: this leaves inconsistent terminology around "model" and
"firmware manifest key", which is quite intentional at the moment,
since the model is still the firmware manifest key for the time
being.  Should we decide to change that in the future, we can do
further renaming in futility.
