Add X25519 to the default set of curves
Since many clients default to the X25519 curve in the TLS handshake, the fact that the server by defualt doesn't support it cause an extra roundtrip for each TLS connection. By adding multiple curves, which is supported since 3d1ef3a15c3eb68da, we can reduce the risk of extra roundtrips.
