bridge cni: Make sure to create the directory for cni config

[afbjorklund]

Otherwise it will be created with the mktemp permissions
and become unreadable (0700), making chmod fail later on.

Fixes error seen in #10852 (comment)

💣 Error starting cluster: apply cni: cni apply: copy: chmod /etc/cni/net.d/1-k8s.conf: permission denied
