ndisc: honor IPv6AcceptRA.UseDNS when parsing RA options (#5071)
RDNSS and DNSLL options received in RA are always used, possibly breaking the resolution of private domains hosted on a local DNS server. When setting UseDNS=no in a [IPv6AcceptRA] section of a .network file, both RDNSS and DNSLL options in received RA should be ignored.
Fixes: #5040
