bpf: fix samples xdp_tx_iptunnel and tc_l2_redirect with fake KBUILD_…

…MODNAME Fix build errors for samples/bpf xdp_tx_iptunnel and tc_l2_redirect, when dynamic debugging is enabled (CONFIG_DYNAMIC_DEBUG) by defining a fake KBUILD_MODNAME. Just like Daniel Borkmann fixed other samples/bpf in commit 96a8eb1 ("bpf: fix samples to add fake KBUILD_MODNAME"). Fixes: 12d8bb6 ("bpf: xdp: Add XDP example for head adjustment") Fixes: 90e0289 ("bpf: Add test for bpf_redirect to ipip/ip6tnl") Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
