bpf: Add a new kfunc for cgroup1 hierarchy
A new kfunc is added to acquire cgroup1 of a task:
- bpf_task_get_cgroup1
Acquires the associated cgroup of a task whithin a specific cgroup1
hierarchy. The cgroup1 hierarchy is identified by its hierarchy ID.
This new kfunc enables the tracing of tasks within a designated
container or cgroup directory in BPF programs.
