rGd3f2c31b43b7: traceroute6: Fix Capsicum rights for rcvsock
rGb8ae450f05e6: traceroute6: Fix Capsicum rights for rcvsock
Summary
  • Always use distinct sockets for send and recv
  • Limit rights on the recv socket
  • Limit rights before entering capability mode

For ICMP6 we were using the same socket for both, and we limited rights
on the socket such that it's impossible to receive anything.

It looks good entering capability mode before limiting rights. So no need to adjust here.
