Subject: [PATCH] cgroup: Fix CGROUP_BPF config dependency when !NET

CGROUP_BPF selects SOCK_CGROUP_DATA which depends on NET

So, if NET is not set the following warning is given:

warning: (CGROUP_BPF) selects SOCK_CGROUP_DATA which has unmet direct
dependencies (NET)

Fix it by making CGROUP_BPF dependent of NET
