Restore support for "Override local DNS" (#2438 )

Tailscale allows to override the local DNS settings of a node via
"Override local DNS" [1]. Restore this flag with the same config setting
name `dns.override_local_dns` but disable it by default to align it with
Tailscale's default behaviour.

Tested with Tailscale 1.80.2 and systemd-resolved on Debian 12.

With `dns.override_local_dns: false`:

```
Link 12 (tailscale0)
Current Scopes: DNS
     Protocols: -DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
   DNS Servers: 100.100.100.100
    DNS Domain: tn.example.com ~0.e.1.a.c.5.1.1.a.7.d.f.ip6.arpa [snip]
```

With `dns.override_local_dns: true`:

```
Link 12 (tailscale0)
Current Scopes: DNS
     Protocols: +DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
   DNS Servers: 100.100.100.100
    DNS Domain: tn.example.com ~.
```
