Curtis Dunham b7d072b235 dist, dev: fix etherswitch upgrade script
The aforementioned upgrader in [1] assumes every option in [system]
has a delimiting '.', and also seems to do its rewriting work a bit too
unconditionally.  Most checkpoints in the wild don't have this device,
in which case this script should be a safe no-op.
