nixos/yggdrasil: change config priority, persistentKeys

Favor the configuration in "configFile" over "config" to allow
"configFile" to override "config" without a system rebuild.

Add a "persistentKeys" option to generate keys and addresses that
persist across service restarts. This is useful for self-configuring
boot media.
