json-c 0.19 frees a container object in json_object_put() in a call
inside assert(). The package builds with NDEBUG, which compiles that
call out, so every released object or array stays allocated. Each
json() of ucode leaks its result this way: netifd grew to 58 MB and a
test agent to 80 MB within a day, and a 352 MB device ran out of memory.
Add a patch that calls the function before the assertion.
