Enabling the bpf feature for the standard kernel configurations
by default. Systemd (and other) userspace applications are looking
for BPF more often, and we get warnings such as this:
[ 12.810554] systemd[1]: File
/lib/systemd/system/systemd-journald.service:36 configures an IP
firewall (IPAddressDeny=any), but the local system does not support
BPF/cgroup based firewalling.
The configs don't add much overhead to the kernel, so we enable them
by default.
