libvirt_nss_macs: Fix type of @len in findMACsFromJSON()

Inside of findMACsFromJSON(), the retval of
json_object_array_length() is stored in a variable that's type of
int. But the function is declared to return size_t:

  /usr/include/json-c/json_object.h:JSON_EXPORT size_t json_object_array_length(const struct json_object *obj);

Fix the type of the local variable.
