samples: bpf: Convert xdp_redirect_map_multi_kern.o to XDP samples helper
One of the notable changes is using a BPF_MAP_TYPE_HASH instead of array
map to store mac addresses of devices, as the resizing behavior was
based on max_ifindex, which unecessarily maximized the capacity of map
beyond what was needed.
