selftests/bpf: Add testcase for bpf_task_under_cgroup
test_progs:
Tests new kfunc bpf_task_under_cgroup().
The bpf program saves the new task's pid within a given cgroup to
the remote_pid, which is convenient for the user-mode program to
verify the test correctness.
The user-mode program creates its own mount namespace, and mounts the
cgroupsv2 hierarchy in there, call the fork syscall, then check if
remote_pid and local_pid are unequal.
