selftests/bpf: Properly enable hwtstamp in xdp_hw_metadata
The existing timestamping_enable() is a no-op because it applies
to the socket-related path that we are not verifying here
anymore. (but still leaving the code around hoping we can
have xdp->skb path verified here as well)

Also, maybe something to archive here, see [0] for Jesper's note
about NIC vs host clock delta.
