bpf: Introduce cgroup_{common,current}_func_proto
Split cgroup_base_func_proto into the following:
* cgroup_common_func_proto - common helpers for all cgroup hooks
* cgroup_current_func_proto - common helpers for all cgroup hooks
running in the process context (== have meaningful 'current').
Move bpf_{g,s}et_retval and other cgroup-related helpers into
kernel/bpf/cgroup.c so they closer to where they are being used.
