bpf: Sync kernel ABI header with tooling header for bpf_common.h

bpf: Sync kernel ABI header with tooling header for bpf_common.h

I recently fixed up a lot of commits that forgot to keep the tooling
headers in sync.  And then I forgot to do the same thing in commit
2aee9bf77bca ("bpf: add comments to BPF ld/ldx sizes"). Let correct
that before people notice ;-).

Lawrence did partly fix/sync this for bpf.h in commit 2d21e76e500d
("bpf: add selftest for tcpbpf").

Fixes: 2aee9bf77bca ("bpf: add comments to BPF ld/ldx sizes")
