Update embedded jsoncpp from unk version to 0.10.6 + move libs to lib/ instead of src/ (#5473)
* Update embedded jsoncpp from unk version to 0.10.6
0.10.6 is last release without c++11
* Make jsoncpp more compliant with its amalgamate
Jsoncpp cpp file should be upper, make the library like it does in amalgamate
* Reorganization: move minetest embedded libs outside of source tree to /lib
* Fix a dead grep in LINT
