bump hbb_common: drop link-local IPv6 from ICE gathering

Also pin webrtc-util to a fork of 0.11.0 carrying a Windows IPv6 enumeration fix.
`ifaces` reads the adapter list's on-wire IPv6 bytes as host-order `[u16; 8]`, so on a
little-endian host every group comes out byte-swapped and unbindable: a peer's real
240e:369:9606:4600:f52a:7a8d:2530:4de0 is enumerated as e24:6903:696:46:2af5:8d7a:3025:e04d,
::1 as ::100 and fe80:: as 80fe::. Each fails to bind with WSAEADDRNOTAVAIL, so ICE gathers
no IPv6 host candidate at all on Windows - where a globally routable address is the one
NAT-free path a CGNAT'd peer has.

Never reported upstream; the unix twin of the same bug was fixed in webrtc-rs#475 (2023).
Fork: rustdesk-org/webrtc, branch rustdesk-patches, tag webrtc-util-0.11.0-win-ipv6.
