    build: conditionally enable testing-kernel feature
    
    Only enable the testing-kernel feature for the target when the testing
    kernel version does not match the stable kernel version.
    
    This way, the option for building the testing kernel in the build config
    menu is only exposed when there's a testing kernel available.
