selftests: net: declare section names for bpf_offload
Non-ancient ip (iproute2-5.15.0, libbpf 0.7.0) refuses to load
the sample with maps because we don't generate BTF:
libbpf: BTF is required, but is missing or corrupted.
ERROR: opening BPF object file failed
Enable BTF by adding -g to clang flags. With that done
neither of the programs load:
libbpf: prog 'func': error relocating .BTF.ext function info: -22
libbpf: prog 'func': failed to relocate calls: -22
libbpf: failed to load object 'ksft-net-drv/net/sample_ret0.bpf.o'
Andrii explains that this is because we don't specify
section names for the code. Add the section names, too.
