In the past we incorrectly handled eBPF errors in two ways:
1. We would only ignore errors if there was an allow rule in the list
(this doesn't make sense because for security purposes we only care
if a *deny* rule is being ignored). Arguably this is a security flaw
but you would only get an error from bpf(2) in rare cases, and thus
is not a big enough deal to go through security review.
2. If we were in a rootless container we would still return an error
even though bpf(2) is blocked for rootless containers.
