Merge pull request #30556 from ixdy/kubekins-test-bc

Automatic merge from submit-queue

Install bc in the kubekins-test image

I finally figured out those
```
/dev/fd/63: line 124: bc: command not found
/dev/fd/63: line 125: bc: command not found
```
lines that keep appearing in build logs.

Image is not yet pushed.
