openvpn: T9364: default the MTU to 1420 when DCO is enabled
The ovpn Kernel module does no MSS clamping, so with a 1500 bytes MTU
full sized packets get fragmented on the underlay.
Add an "mtu" node, rendered as "tun-mtu". With "offload dco" it
defaults to 1420, unless a raw tun-mtu/link-mtu/udp-mtu option is
present. Reject "mtu" together with such an option, below 100, and
below 1280 when IPv6 runs inside the tunnel.
