Preinstalled overlays needn't be signed with the same cert
as the package it overlays, simply being preinstalled is
enough. Sign with the default cert instead for now, which
provides fewer special privileges.

The new trafficController design is based on per-cgroup eBPF filter as well as xt_bpf netfilter module inside the kernel.
However, support for per-cgroup eBPF is available on only on kernels >=4.9 . Disable BPF offloading support completely
as without proper per-cgroup eBPF, the stats returns errors continuously.
