Volker Lendecke f60780c8b6 libcli/dns: Fix TCP fallback

A customer has come across a DNS server that really just cuts a SRV
reply if it's too long. This makes the packet invalid according to
ndr_pull and according to wireshark. DNS_FLAG_TRUNCATION is however
set. As this seems to be legal according to the DNS RFCs, we need to
hand-parse the first two uint16's and look whether DNS_FLAG_TRUNCATION
is set.
