wg-quick leaking DNS on Fedora33

[Mattias Eriksson]

Since wg-quick doesn't support systemd-resolved, which Fedora 33 have 
enabled by default, it will fail to set the DNS correctly. I have filed 
a bug against Fedora 33.
https://bugzilla.redhat.com/show_bug.cgi?id=1884352  , but I don't know 
how responsive they are regarding wireguard so it might be something 
for you guys to look at.
