Merge branch 'Use lightweigt version of bpftool'
Pu Lehui says:
====================
Currently, samples/bpf, tools/runqslower and bpf/iterators use bpftool
for vmlinux.h, skeleton, and static linking only. We can use lightweight
bootstrap version of bpftool to handle these, and it will be faster.
v2:
- make libbpf and bootstrap bpftool independent. and make it simple.
v1: https://lore.kernel.org/bpf/20220712030813.865410-1-pulehui@huawei.com
