main/wireguard-tools: allow installing other providers of resolvconf

This allows downstream (postmarketOS) to use wg-quick with
systemd-resolved, which also provides a resolvconf tool that is
compatible with wg-quick. There should be no impact to Alpine installs
with this change, resolvconf in aports still comes from openresolv
