tools: ynl: extend netdev sample to dump xdp-rx-metadata-features

The tool can be used to verify that everything works end to end.

Unrelated updates:
- include tools/include/uapi to pick the latest kernel uapi headers
- print "xdp-features" and "xdp-rx-metadata-features" so it's clear
  which bitmask is being dumped
