[refactor] Move third party code to its own dir

Jsonxx is an import of a third party code, with its own license. While
the licenses are compatible, moving that code to its own directory make
it easier to identify it as foreign.

This commit also remove the extra copy of the code that was in the
repository, and update the relevant Makefile rules.
