libbpf, selftests/bpf: Adjust libbpf, bpftool, selftests to match LLVM
The selftests use
to tell LLVM about special pointers. For LLVM there is nothing "arena"
about them. They are simply pointers in a different address space.
Hence LLVM diff https://github.com/llvm/llvm-project/pull/85161 renamed:
. macro __BPF_FEATURE_ARENA_CAST -> __BPF_FEATURE_ADDR_SPACE_CAST
. global variables in __attribute__((address_space(N))) are now
placed in section named ".addr_space.N" instead of ".arena.N".
Adjust libbpf, bpftool, and selftests to match LLVM.
