This patch add a xdp program on egress to show that we can modify
the packet on egress. In this sample we will set the pkt's src
mac to egress's mac address. The xdp_prog will be attached when
-X option supplied.

Users should try use the new BTF defined maps instead of struct
bpf_elf_map defined maps. The tail call examples are not added yet
as libbpf doesn't currently support declaratively populating tail call
maps.

The tcbpf2_kern.o and related kernel sections are moved to bpf
selftest folder since b05cd7404323 ("samples/bpf: remove the bpf tunnel

currect framework simplified it in purpose, I also removed unused tcp
