Callers need to know the alias anyways so it does not make much sense to
generate it inside of this function.
Note that there's a lingering bad design of this, since the secret
object alias is based on the device name and not on the fact that the
secret is used for decrypting of the TLS private key. If we ever add
authentication for chardevs this will bite us.
Thankfully disk code does not support encrypted private keys for TLS so
it can be happily refactored there.
