Fix bug when resulted in NXDOMAIN answers instead of NODATA.
check_for_local_domain() was broken due to new code matching F_*
bits in cache entries for DNSSEC. Because F_DNSKEY | F_DS is
used to match RRSIG entries, cache_find_by_name() insists on an exact match
of those bits. So adding F_DS to the bits that check_for_local_domain()
sends to cache_find_by_name() won't result in DS records as well
as the others, it results in only DS records. Add a new bit, F_NSIGMATCH
which suitably changes the behaviour of cache_find_by_name().
