This patch removes the obsolete cgroup related tests. These tests are
now redundant because their functionality is already covered by more
modern and comprehensive tests under selftests/bpf.
The following files are removed:
- test_current_task_under_cgroup: tests bpf_current_task_under_cgroup()
to check if a task belongs to a cgroup. Already covered by
task_under_cgroup at selftest and other cgroup ID tests.
- test_cgrp2_tc: tests bpf_skb_under_cgroup() to filter packets based
on cgroup. This behavior is now validated by cgroup_skb_sk_lookup,
which uses bpf_skb_cgroup_id, making this test redundant.
By removing these outdated tests, this patch helps streamline and
modernize the test suite, avoiding duplication of test coverage.
