[PATCH] wireguard-tools: allow generating private_key

[Leonardo Mörlein]

When the uci configuration is created automatically during a very early
stage, where no entropy daemon is set up, generating the key directly is
not an option. Therefore we allow to set the private_key to "generate"
and generate the private key directly before the interface is taken up.
