jansson: Backport fixes to bundled, use json_vsprintf if available.

Use json_vsprintf from versions which contain fix for va_copy leak.

Apply fixes from jansson master:
* va_copy leak fix.
* Avoid potential invalid memory read in json_pack.
* Rename variable that shadowed another.

Subject: [PATCH 25/29] Call va_end after va_copy in json_vsprintf
As said in man doc:
"Each invocation of va_copy() must be matched by a corresponding
invocation of va_end() in the same function."
va_copy may alloc memory in some system, it's necessay to free it by
va_end.
Fixes: efe6c7b3f2b3 ("Add json_sprintf and json_vsprintf")
