    Check if file is present instead of directory
    
    Fixes #8886.
    
    Problem: any `sync-all` command that is run before the first succesfull
    `sync-all get` would trigger a false warning about an old `time` package
    being present.
    
    Cause: after cloning the ghc repository, the (empty) `libraries/time`
    directory is already present.
    
    Solution: check if the directory actually contains any of the `time`
    files. I picked the `LICENSE` file, since `boot` does so as well.
