selftests/bpf: test_xdp_redirect: Rename BPF sections

SEC("redirect_to_111") and SEC("redirect_to_222") can't be loaded by the
__load() helper.

Rename both sections SEC("xdp") so it can be interpreted by the __load()
helper in upcoming patch.
Update the test_xdp_redirect.sh to use the program name instead of the
section name to load the BPF program.
