Aleksa Sarai 4dc207a6c0 cgroupv2: ebpf: ignore inaccessible existing programs

This is necessary in order for runc to be able to configure device
cgroups with --systemd-cgroup on distributions that have very strict
SELinux policies such as openSUSE MicroOS[1].

The core issue here is that systemd is adding its own BPF policy that
has an SELinux label such that runc cannot interact with it. In order to
work around this, we can just ignore the policy -- in theory this
behaviour is not correct but given that the most obvious case
(--systemd-cgroup) will still handle updates correctly, this logic is
reasonable.
