bpf: wireguard: set SKIP_SRV6_HANDLING

The wireguard program includes srv6.h via nodeport.h, but doesn't actually
need any of the SRv6 code (since it's all guarded by IS_BPF_LXC inside
nodeport.h).

Match what we do for bpf_overlay and bpf_xdp to avoid even compiling these
tailcalls, even though nowadays they should simply be eliminated at load
time.
