Set Czech (cs) and Slovak (sk) as reciprocal fallbacks

The two languages are mutually intelligible at a very high degree and
most speakers can be considered bilinguals or passive bilinguals.

Consulted resources:
* Eurostat special eurobarometer 386 (2012).

* Mira Nábělková
** http://doai.io/10.1515/IJSL.2007.004: «These differences do not prevent the users of Slovak and
   Czech from understanding discourse in the other language [...]. While contact with Czech texts
   in the Slovak environment is obvious, it does not appear to be so in the opposite case.»
** High degree of passive bilingualism even in recent generations who don't feel it much.
