[Lognorm] Minor issue with liblognorm 1.0.0 release.

[Pavel Levshin]

Hello,

Could you please explain, why pkg_config does not work well in your 
case? It should set correct -I option and find the header automagically. 
Unless json.pc (pkg_config description file) is incorrect on 
distribution you are using.

Anyway, your solution will probably break with next release of json-c:

0.11
   * IMPORTANT: the name of the library has changed to libjson-c.so and
      the header files are now in include/json-c.
      The pkgconfig name has also changed from json to json-c.
      You should change your build to use appropriate -I and -l options.
      A compatibility shim is in place so builds using the old name will
      continue to work, but that will be removed in the next release.
