Fix an issue about generation of secret key with invalid key size in gce

Replace /dev/random to /dev/urandom to avoid generation of secret key with invalid key size.



**What this PR does / why we need it**:
In GCE env, AESGCM encryption of secrets by default generates a secret key with /dev/random which sometime generates a key with invalid size.
This cause the cluster/kube-up.sh to fail in gce environment.

This PR replaces /dev/random with  /dev/urandom to have a secret key generated consistently with right size.

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes #67091

**Special notes for your reviewer**:

**Release note**:

```release-note
cluster/gce: generate consistent key sizes in config-default.sh using /dev/urandom instead of /dev/random

Cluster Configuration

Deprecation Notice: This directory has entered maintenance mode and will not be accepting new providers. Please submit new automation deployments to kube-deploy. Deployments in this directory will continue to be maintained and supported at their current level of support.

The scripts and data in this directory automate creation and configuration of a Kubernetes cluster, including networking, DNS, nodes, and master components.

See the getting-started guides for examples of how to use the scripts.

cloudprovider/config-default.sh contains a set of tweakable definitions/parameters for the cluster.

The heavy lifting of configuring the VMs is done by SaltStack.
