Subject: [PATCH v3 06/12] arm64: defconfig: enable bpf/cgroup firewalling

From: Marcel Ziswiler <marcel.ziswiler@...adex.com>

This avoids the following systemd warning:

[    2.618538] systemd[1]: system-getty.slice: unit configures an IP
 firewall, but the local system does not support BPF/cgroup firewalling.
[    2.630916] systemd[1]: (This warning is only shown for the first
 unit using IP firewalling.)
