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
96a8eb1eeed2 ("bpf: fix samples to add fake KBUILD_MODNAME").
Fixes: 12d8bb64e3f6 ("bpf: xdp: Add XDP example for head adjustment")
Fixes: 90e02896f1a4 ("bpf: Add test for bpf_redirect to ipip/ip6tnl")
