Subject: [PATCH bpf-next v3 5/6] selftests/bpf: Unify memory address casting operation style

The members of bpf_prog_info, which are line_info and jited_line_info
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.
