[PATCH] examples: drop legacy json-c support

[Sergey Ponomarev]

The cmake logic is wrong (E.G. PKG_CHECK_FOR_MODULES fails unless all modules are found), and the legacy libjson.so name is also used by the other libjson (http://sourceforge.net/projects/libjson/) which provides an incompatible API, so just drop it.
