Set Pi-hole to "Listen on all interfaces, permit all origins" when using it as DNS for the VPN

Browse source 
- Letting dnsmasq additionally listen on a specific VPN interface when Pi-hole is
    listening on the physical interface only may be more secure than letting dnsmasq
    listen on all interfaces, however, dnsmasq will stop listening on the physical
    interface (breaking LAN resolution) if the user changes the listening behavior
    at a later time.
    For the target audience of PiVPN, it is more likely that users will set the
    listening behavior to all when deciding to use Pi-hole via VPN (which is suggested
    in the Pi-hole guide and most guides on the web), instead of digging into
    configuration file.
    This option is safe if the Raspberry Pi is inside the local network and the user
    has not forwarded port 53 on their router, which is unlikely as they are installing
    PiVPN precisely to avoid doing that.
