Marco Ballesio f46d7a26c1 sepolicy: rules for uid/pid cgroups v2 hierarchy
the cgroups v2 uid/gid hierarchy will replace cgroup for all sepolicy
rules. For this reason, old rules have to be duplicated to cgroup_v2,
plus some rules must be added to allow the ownership change for cgroup
files created by init and zygote.

Test: booted device, verified correct access from init, system_server
and zygote to the uid/pid cgroup files
