bpf: cgroup: Fix build error without CONFIG_NET

If CONFIG_NET is not set and CONFIG_CGROUP_BPF=y,
gcc building fails:

kernel/bpf/cgroup.o: In function `cg_sockopt_func_proto':
cgroup.c:(.text+0x237e): undefined reference to `bpf_sk_storage_get_proto'
cgroup.c:(.text+0x2394): undefined reference to `bpf_sk_storage_delete_proto'
kernel/bpf/cgroup.o: In function `__cgroup_bpf_run_filter_getsockopt':
(.text+0x2a1f): undefined reference to `lock_sock_nested'
(.text+0x2ca2): undefined reference to `release_sock'
kernel/bpf/cgroup.o: In function `__cgroup_bpf_run_filter_setsockopt':
(.text+0x3006): undefined reference to `lock_sock_nested'
