Use a non-error log level for normal status evaluation.

This helper runs during normal reconciliation and emits at least two ERROR records on every path. Replace the added klog.Errorf calls with klog.Infof or klog.V(4).Infof. Reserve error-level logging for actual failures.

minimal, and validate.

In `@pkg/controller/build/helpers.go` around lines 129 - 135, The status
evaluation logs in isMachineOSBuildStatusUpdateNeeded are normal reconciliation
diagnostics, not failures; replace the added klog.Errorf calls with an
informational level such as klog.Infof or klog.V(4).Infof while preserving their
messages.
