selftests/bpf: fix compiling loop{1, 2, 3}.c on s390
Use PT_REGS_RC(ctx) instead of ctx->rax, which is not present on s390. Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com> Reviewed-by: Stanislav Fomichev <sdf@google.com> Tested-by: Stanislav Fomichev <sdf@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
