[mattisafur]

fixes #19931

when running:
$ minikube logs --file log.txt --last-start-only
or
$ minikube logs --file log.txt --audit

before:

• outputs requested log to stdout
• creates a blank log.txt file

after:

• outputs requested log to file
• no output to stdout

I'm pretty new to go, let me know if there's something I should change.

Hi @mattisafur. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
