Various tests will call UninstallCiliumFromManifest() ->
DeleteAndWait() during cleanup, including when the test itself gets
skipped. When running individual test cases from kind, this can mean
that the file that is supposed to contain the Cilium configuration
doesn't exist on the local filesystem, and then when attempting to
delete that Cilium configuration from the cluster, the tesuite reports:
Fix this by looking to see whether the file even exists. If we never
properly configured Cilium in the first place, then the file won't
exist, and then it's safe to just no-op the uninstall process.
