Jesper Dangaard Brouer e8163b98d9 selftests/bpf: xdp_hw_metadata remove bpf_printk and add counters
The tool xdp_hw_metadata can be used by driver developers
implementing XDP-hints metadata kfuncs.

Remove all bpf_printk calls, as the tool already transfers all the
XDP-hints related information via metadata area to AF_XDP
userspace process.

Add counters for providing remaining information about failure and
skipped packet events.
