[PATCH bpf-next 4/5] bpf: remove the cgroup -> bpf header dependecy

[Jakub Kicinski <kuba@kernel.org>]

Now that the stage has been set and actors are in place
remove the header dependency between cgroup and bpf.h.

This reduces the incremental build size of x86 allmodconfig
after bpf.h was touched from ~17k objects rebuilt to ~5k objects.
bpf.h is 2.2kLoC and is modified relatively often.
