Add bpf_program__clone() API that loads a single BPF program from a prepared BPF object into the kernel, returning a file descriptor owned by the caller. After bpf_object__prepare(), callers can use bpf_program__clone() to load individual programs with custom bpf_prog_load_opts, instead of loading all programs at once via bpf_object__load(). Non-zero fields in opts override the defaults derived from the program and object internals; passing NULL opts populates everything automatically.
