jplist: Fix OOB read in parse_primitive caused by missing 0-termination
In parse_primitive, integer and double values are parsed by using strtoll
and atof, which both expect the string to be 0-terminated. While this is
not a problem in well-formed JSON files, it can be if the JSON data is not,
possibly leading to a crash due to OOB memory access.
This commit fixes it by copying the value data in question to a stack buffer
and 0-terminate it, and use that buffer instead.
