zygote: Add setattr permission to cgroup

Credit to Himanshu Agrawal <quic_hagraw@quicinc.com> for this fix.

Like we do with cgroup_v2, we set attribute permission to cgroup
as well.

This is the same fix as
https://android-review.googlesource.com/c/platform/system/sepolicy/+/1927857/
but it applies it to the prebuilts for api 32.0.

Test: On a Go device, which uses cgroup instead of cgroup_v2
