net: Get rcv tstamp if needed in nfnetlink_{log, queue}.c
If skb has the (rcv) timestamp available, nfnetlink_{log, queue}.c
logs/outputs it to the userspace. When the locally generated skb is
looping from egress to ingress over a virtual interface (e.g. veth,
loopback...), skb->tstamp may have the delivery time before it is
known that will be delivered locally and received by another sk. Like
handling the delivery time in network tapping, use ktime_get_real() to
get the (rcv) timestamp. The earlier added helper skb_tstamp_cond() is
used to do this. false is passed to the second 'cond' arg such
that doing ktime_get_real() or not only depends on the
netstamp_needed_key static key.
