After much poking around, reverse engineering, looking at ICU's Makefiles,
I found that the following works:

  $ echo utr30.nrm | gencmn -v -n utr30 0  # big endian since utr30.nrm is
  $ icupkg -tl utr30.dat ../utr30.dat      # convert to little endian

   then in Python, using the newest, little endian, utr30.dat if you are
   on a little endian platform

  >>> ResourceBundle.setAppData("utr30", "utr30.dat")
  >>> Normalizer2.getInstance("utr30", "utr30", UNormalizationMode2.COMPOSE)

I'm not sure that this is the best way but it seems to work.
