anet upgrade fix

The anet dependency is deeply embedded — it's pulled in by go-libp2p, kubo, boxo, ipfs-cluster, and many others, all through pion's webrtc
  transport. There's no way to avoid it without reverting the entire update.

  The fix is to pass -checklinkname=0 to the linker in your gomobile build command:

  gomobile bind -ldflags="-checklinkname=0" -target=android ./mobile/

  This disables Go 1.23+'s strict //go:linkname checking. The anet package uses //go:linkname net.zoneCache to work around Android 11+ SELinux
  restrictions on network interface enumeration — it's intentional and necessary, but the Go linker started rejecting it. This is the same
  workaround syncthing/syncthing#10211 for their Android builds.

  The upstream fix will come when either:
  - The anet maintainer removes the //go:linkname directives (wlynxg/anet#11)
  - Go's stdlib fixes net.Interfaces() on Android directly (golang/go#68082)
