update cilium/ebpf to fix haveBpfProgReplace() check

The `errors.Is(err, unix.EINVAL)` check in `haveBpfProgReplace()` was
broken because the `cilium/ebpf` library did not "wrap" errors.
https://github.com/cilium/ebpf/blob/v0.6.0/link/program.go#L72

So the eBPF support of runc was broken for kernel prior to 5.6.

This commit bumps up cilium/ebpf to contain cilium/ebpf PR 320.

Fix opencontainers/runc issue 3008
