Jakub Sitnicki 33a971d549 selftests/bpf: Add LWT encap tests for skb metadata
Test that an LWT encapsulation does not silently corrupt XDP metadata
sitting in the skb headroom. Exercise all three LWT dispatch paths:

- BPF LWT xmit prog reserves headroom on the LWT .xmit redirect,
- mpls pushes an MPLS label on the LWT .xmit redirect,
- seg6 in encap mode runs on the LWT .input redirect,
- ioam6 encap inserts an IOAM Hop-by-Hop option on LWT .output redirect.
