logcheck doesn't handle Exit* functions correctly

[serathius]

/kind bug

klog defines set of functions Exit, Exitf, Exitln, ExitDepth. Those functions are not correctly handled by logcheck. kubernetes/kubernetes#103293 (comment)

What steps did you take and what happened:

When running logcheck to validate log calls, it reported Exitf as structured logging method

/home/prow/go/src/k8s.io/kubernetes/test/images/apparmor-loader/loader.go:64:3: structured logging function "Exitf" should not use format specifier "%s"

What did you expect to happen:

I would expect that logcheck will ignore this method when in allow-unstructured mode and report it as error only when allow-unstructured is off.

Anything else you would like to add:
