fix: missing k3s volumeMounts (#533)

Possibly due to the fix in https://github.com/squat/kilo/pull/520 not
falling back to a valid value anymore, the following error reproduces on
k3s now:

    failed to create Kubernetes config: invalid configuration: unable to read certificate-authority /var/lib/rancher/k3s/agent/server-ca.crt for kilo due to open /var/lib/rancher/k3s/agent/server-ca.crt: no such file or directory

This adds the mounts for volumes that are already available
