clatd: remove ipv6 address monitoring
This code/logic is spurious, because the majority of packets
are translated by eBPF, so whether the daemon runs or not,
usually just doesn't matter - bpf will handle them anyway.
As such what we actually care about is that the daemon
is terminated at the same time as the bpf map configuration
is removed. This is done by jni native code stopClatdProcess()
which is called from ClatCoordinator java code immediately
after maybeStopBpf().
Additionally on ipv6 address change we don't even terminate
the daemon - we simply stop the event loop, but still block
in main() until we receive SIGTERM/SIGKILL.
(This was done a while ago to fix a bunch of issues with
daemon dieing and being killed racing with each other)
