Subject: [PATCH] Replace writepid with task_profiles command for cgroup
 migration

writepid command usage to join a cgroup has been deprecated in favor
of a more flexible approach using task_profiles. This way cgroup path
is not hardcoded and cgroup changes can be easily made. Replace
writepid with task_profiles command to migrate between cgroups.

Bug: 191283136
Test: build and boot
