Subject: [PATCH bpf-next v2 5/5] selftests/bpf: Change the casting about jited_ksyms and jited_linfo

We have unified data extension operation of jited_ksyms and jited_linfo
into zero extension [0], so there's no need to cast __u64 memory address
to long data type. And __u64 in some arch is unsigned long, so to avoid
compiler warnings we just cast them to unsigned long long.
