dns/dnsmasq-devel: update to 2.87test9

CHANGELOG difference in Git between test8 and test9

• Enhance --domain to accept, for instance, --domain=net2.thekelleys.org.uk,eth2 so that hosts get a domain which relects the interface they are attached to in a way which doesn't require hard-coding addresses. Thanks to Sten Spans for the idea.

• Fix write-after-free error in DHCPv6 server code. CVE-2022-0934 refers.

• Add the ability to specify destination port in DHCP-relay mode. This change also removes a previous bug where --dhcp-alternate-port would affect the port used to relay _to_ as well as the port being listened on. The new feature allows configuration to provide bug-for-bug compatibility, if required. Thanks to Damian Kaczkowski for the feature suggestion.

• Bound the value of UDP packet size in the EDNS0 header of forwarded queries to the configured or default value of edns-packet-max. There's no point letting a client set a larger value if we're unable to return the answer. Thanks to Bertie Taylor for pointing out the problem and supplying the patch.

• Fix problem with the configuration
  
  --server=/some.domain/# --address=/#/<ip> --server=<server_ip>
  
  This would return <ip> for queries in some.domain, rather than forwarding the query via the default server.
