cros_update_firmware: Append uris to srcuris if --project is set.

- The main use case is to do a fw uprev w/o having access to all
project repos. If the file is overwritten in this case, some uris
will be deleted.

- This will mean extra payloads are downloaded, but won't be
installed in the image.

- Only enable this if --project flag is set, so it likely won't
affect users that can see all projects. Add append_srcuris flag
to disable this with the --project flag if needed.
