perf bpf: Add linux/socket.h to the headers accessible to bpf proggies
So that we don't have to define sockaddr_storage in the augmented_syscalls.c bpf example when hooking into syscalls needing it, idea is to mimic the system headers. Eventually we probably need to have sys/socket.h, etc. Start by having at least linux/socket.h.
