selftests/bpf: Re-generate vmlinux.h and BPF skeletons if bpftool changed
[ Upstream commit cab62c37be057379a2a17b1b2eacd9dcba1e14dc ]
Trigger vmlinux.h and BPF skeletons re-generation if detected that bpftool was
re-compiled. Otherwise full `make clean` is required to get updated skeletons,
if bpftool is modified.
