[PATCH net-next 0/2] samples, bpf: Refactor; Add automated tests for cgroups

[Sargun Dhillon <sargun@sargun.me>]

These two patches are around refactoring out some old, reusable code from the 
existing test_current_task_under_cgroup_user test, and adding a new, automated 
test.

There is some generic cgroupsv2 setup & cleanup code, given that most 
environment still don't have it setup by default. With this code, we're able
to pretty easily add an automated test for future cgroupsv2 functionality.
