Parser: set *len = 0 in the last string chunk

Probably a good idea anyway, plus solves a false positive warning:

 src/compilersupport_p.h:192:34: error: ‘chunkLen’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
     return __builtin_add_overflow(v1, v2, r);
            ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~
 src/cborparser.c:1163:16: note: ‘chunkLen’ was declared here
         size_t chunkLen = chunkLen;
                ^~~~~~~~
