[MODULE] DNS.Watch for Magisk 17+

[nxb]

So override dns isn't working in Magisk. I needed to change DNS to something that's not google or cisco. Maybe cloudflare is close but DNS.watch isn't US based. In the repo there isn't much choice so I edited cloudflare and made it set IPv4 and IPv6. Now you're covered for both.

I'm using Nougat 7.1.2 and it works. Checked on dnsleaktest.com in Firefox.
