package/json-c: fix build with CMake 4

The build of host-json-c currently fails due to the move to CMake
4. However, we don't need to patch the problem, as we can instead
disable building the json-c applications (-DBUILD_APPS=OFF) for the
host variant like we already do for the target variant.

Fixes:
