nixos/acme: don't use --reuse-key

Reusing the same private/public key on renewal has two issues:

 - some providers don't accept to sign the same public key
   again (Buypass Go SSL)

 - keeping the same private key forever partly defeats the purpose of
   renewing the certificate often

Therefore, let's remove this option. People wanting to keep the same
key can set extraLegoRenewFlags to `[ --reuse-key ]` to keep the
previous behavior. Alternatively, we could put this as an option whose
default value is true.
