network-ndisc: avoid VLAs (#3725)
Do not allocate objects of dynamic and potentially large size on the stack to avoid both clang compilation errors and unpredictable runtime behavior on exotic platforms. Use the heap for that instead. While at it, refactor the code a bit. Access 's->domain' via NDISC_DNSSL_DOMAIN(), and refrain from allocating 'x' independently, but rather reuse 's' if we're dealing with a new entry to the set. Fixes #3717
