Subject: sys/linux: make bpf_link_create_arg a template

Make bpf_link_create_arg a template so that it's possible to create more specialized versions.
Add a specialized version for XDP links. First, they need a special program type,
plus a special attach type and target fd is not an fd, but rather ifindex.
