there is no need to backport this, libbpf has its own release cycle
and it is released from github mirror. And also this doesn't have any
effect, this inheritance between versions in .map file is mostly for
humans, according [0] (and I checked in practice that it doesn't
change anything for libbpf).

So it's good to fix, but no need to bother maintainers to backport it
to stable branches.
