systemd: arrange for volatile /etc/resolv.conf
On sysvinit systems, volatiles is configured to make /etc/resolv.conf symlink to a file in a volatile path, which lets us write to /etc/resolv.conf for read-only-rootfs. For systemd, this isn't set up unless we enable systemd-resolved, which we don't by default. When it's not enabled, create the /etc/resolv.conf symlink and ensure the volatile path is created on boot with tmpfiles.d.
