If you use localhost (or in fact any fixed ip) for a resolver, you don't
need the resolvconf package at all.  Just uninstall it and you won't
need to work around it.

Another thing that can overwrite resolv.conf is DHCP client, if your
relay is on DHCP for some reason.  That can be stopped by configuring
DHCP to *not* ask for DNS info.  With the ISC DHCP client which was the
default one at least until Debian jessie, that's done by editing
/etc/dhcp/dhclient.conf .
