dnsmasq: sysupgrade hook to conditionally preserve dnsmasq.time
conditionally save dnsmasq.time across sysupgrade dnsmasq uses /etc/dnsmasq.time as record of the last known good system time to aid its validation of dnssec timestamps. dnsmasq updates the timestamp on process start/stop once it considers the system time as valid. The timestamp file should be preserved across system upgrade but should not be included as part of normal configuration backups to prevent restores corrupting the current timestamp.
