[RFC bpf-next 2/8] bpf: extend list based insn patching infra to verification layer

Verification layer also needs to handle auxiliar info as well as adjusting subprog start. At this layer, insns inside patch buffer could be jump, but they should have been resolved, meaning they shouldn't jump to insn outside of the patch buffer. Lineration function for this layer won't touch insn
