dnsmasq doesn't receive updated dns servers when running inside ujail

Bind-mounting /tmp/resolv.conf.auto apparently doesn’t forward inotify events arriving from the kernel when resolv.conf.auto was changed (e.g. upstream
DNS
servers were received by a DHCP client or pppd). Restarting dnsmasq or running it without ujail solves the issue.
