bpf: Add base proto function for cgroup-bpf programs
Currently kernel/bpf/cgroup.c contains only one program type and one
proto function cgroup_dev_func_proto(). It'd be useful to have base
proto function that can be reused for new cgroup-bpf program types
coming soon.
Introduce cgroup_base_func_proto().
