nslookup: handle replies without RRs
Under some circumstances, a DNS reply might contain no resource records,
e.g. when a valid domain is queried that does not have records of the
requested type.
Example with nslookup from BIND dnsutils:
$ nslookup -q=SRV example.org
Server: 10.11.12.13
Address: 10.11.12.13#53
Non-authoritative answer:
*** Can't find example.org: No answer
Currently the busybox nslookup applet simply prints nothing after the
"Non-authoritative answer:" line in the same situation.
This change modifies nslookup to either print "Parse error" or "No answer"
diagnostics, depending on the parse_reply() return value.
