The members of bpf_prog_info, which are line_info, jited_line_info, jited_ksyms and jited_func_lens, store u64 address pointed to the corresponding memory regions. Memory addresses are conceptually unsigned, (unsigned long) casting makes more sense, so let's make a change for conceptual uniformity.
