Commit message:

    Work around core_audiospec.t autopkgtest problems with newer Test-Simple
    
    Newer versions of Test-Simple seem to lose the number of tests
    issued in another thread.
    
    Builds run without AUTOMATED_TESTING set, so they don't hit this.
    Emulate that for autopkgtest as well for now.
    
    Closes: #837145
