Title

Porting bcc tools to libbpf

Description

@0xB10C : reviving this old discussion from some two years ago: @rob-scheepens agree that BPF CO-RE and libbpf is the way to go for future tracing programs. I've looked into this a while ago, but it seems libbpf doesn't support USDT tracepoints yet (see https://github.com/iovisor/bcc/issues/3007). However, there was a mention of a soon to be open sourced libusdt library developed and used in production at Meta by @anakryiko [here](https://lore.kernel.org/bpf/CAEf4BzYRLxzVHw00DUphqqdv2m_AU7Mu=S0JF0PZYN40hBvHgA@mail.gmail.com/). Looking forward to testing this once available! _Originally posted by @0xB10C in https://github.com/bitcoin/bitcoin/issues/22006#issuecomment-1072538909_ Now that USDT has been implemented it would be great to give this a try. In this context, I also came across https://github.com/iovisor/bcc/issues/4404, which could help make things easier.
