liuclare 64aad8027a Skip the TUN IPv6 route when the host has no global IPv6 address (#10080)
#9930 made the Xray TUN inbound always request ::/0 in autoSystemRoutingTable
so that IPv6 stops bypassing the tunnel. That only helps a host which actually
holds a globally routable IPv6 address. On any other host it does harm.

With IPv6 disabled the TUN device gets no IPv6 address at all, the kernel
rejects the route with EACCES and the whole inbound fails to start:

  Failed to start: app/proxyman/inbound: failed to start proxy > proxy/tun:
  failed to add system route ::/0 > permission denied

With IPv6 enabled but no global address the route is accepted and the host
gains an IPv6 default route it cannot use. The TUN completes the TCP handshake
locally before dialing the outbound, so IPv6 destinations start to look
reachable and get picked, and the connection then dies at the outbound instead
of failing fast (#10051).

Neither host has IPv6 traffic that could bypass the tunnel, so ::/0 buys them
nothing. Detect a global IPv6 address once while building the config context
and drop ::/0 when there is none. Link-local and unique local addresses do not
count: they never reach the IPv6 internet.
