bind-acme: guard against letsencrypt clients without internal LAN
The acme_zone reactor's first ACL branch iterates nodes that have
letsencrypt/domains and reads their network/internal/ipv4. Until now
that crashed for any node with letsencrypt but no internal LAN — the
node had to either fake a network/internal/ipv4 or skip TLS.

Add a `metadata.get(..., None)` guard to filter such nodes out of this
branch. The wireguard branch below already covers them (any node with
the wireguard bundle gets its wireguard/my_ip into the ACL), so ACME
DNS-01 reachability still works for cross-Internet nodes that join the
fleet via wireguard.

Surfaced by ovh.left4me: dedicated server with no Hetzner/internal
network, reachable from the bind-acme node only via wireguard.
