Add CONFIG_CGROUP_BPF to ensure docker can be started under cgroup v2,
otherwise it would report the following error:
Error: for ... error setting cgroup config for procHooks process:
bpf_prog_query(BPF_CGROUP_DEVICE) failed: invalid argument: unknown
Cgroup v2 device controller has no interface files and is implemented on top
of cgroup BPF. To control access to device files, a user may create bpf programs
of type BPF_PROG_TYPE_CGROUP_DEVICE and attach them to cgroups with
BPF_CGROUP_DEVICE flag.
