bob.kaldi needs to be released again

• The latest stable of bob.kaldi does not depend on kaldi itself (in its conda packaging). Because of this, when people install bob.kaldi, they end up with broken installations: https://groups.google.com/forum/#!topic/bob-devel/gQllGeHeaKc

Now that this package is ported to the new CI, the installation should work. However bob.kaldi was never released after the fix.

• Also, nowhere in the readme or the docs, it says that bob.kaldi works on Linux only: https://groups.google.com/forum/#!topic/bob-devel/X1bbsDs7mwo

@theophile.gentilhomme Could you please update the readme of this package (saying it works on Linux) and then tag a new version of it?

To release, you have to use this script https://gitlab.idiap.ch/bob/bob.admin/blob/master/release/release_bob.py which @pkorshunov developed.
