Bug description
--snat-subnet-routes=true not work

To Reproduce

  1. tailscale up --login-server=http://server_url --accept-routes=true --accept-dns=false --advertise-routes=10.0.0.234/32--snat-subnet-routes=true

  2. headscale routes enable -i 12 -r "10.0.0.234/32"

  3. headscale node route list -i 12
    Route | Enabled
    10.0.0.234/32 | true

Context info
i use tcpdump at one of node(ip:10.0.0.234) :

tcpdump -i ens160 icmp and host 10.0.9.3 -nn -vvv
tcpdump: listening on ens160, link-type EN10MB (Ethernet), capture size 262144 bytes
13:52:26.379681 IP (tos 0x0, ttl 63, id 42914, offset 0, flags [DF], proto ICMP (1), length 84)
10.0.9.3 > 10.0.0.234: ICMP echo request, id 18, seq 93, length 64
13:52:26.379754 IP (tos 0x0, ttl 64, id 29816, offset 0, flags [none], proto ICMP (1), length 84)
10.0.0.234 > 10.0.9.3: ICMP echo reply, id 18, seq 93, length 64
13:52:27.392447 IP (tos 0x0, ttl 63, id 42921, offset 0, flags [DF], proto ICMP (1), length 84)
10.0.9.3 > 10.0.0.234: ICMP echo request, id 18, seq 94, length 64

So, --snat-subnet-routes=true not work

Version of headscale used: v0.17.0-beta4
