A file, package/network/services/dnsmasq/files/50-dnsmasq-migrate-resolv-conf-auto.sh,
was added in commit 6a28552120, but it
does not exit in a way that tells the uci-defaults mechanism that it
succeeded, and so it is not cleaned up after running successfully. Add
an exit 0 to the end to correct that.
