selftests/bpf: Adapt cgroup effective query uapi change
The attach flags is meaningless for effective query and
its value will always be set as 0 during effective query.
Root cg's effective progs is always its attached progs,
so we use non-effective query to get its progs count and
attach flags. And we don't need the remain attach flags
check.
