[tutorials] Add conditional veto for RooFit tutorial requiring dataframe

The `rf618_mixture_models.py` tutorial requires
`df106_HiggsToFourLeptons.py`, becuase this tutorial produces the input
file.

Also, use explicit names to veto the `rf408_RDataFrameToRooFit`
tutorials instead of globbing, which is more fragile because less
`git grep`able.
