Fix Heap-use-after-free in MDnsSdListener::Monitor::run

Use thread join to avoid thread exiting after instance
recycled.

Prior to implementing this patch, fuzzing would lead to a segmentation fault after approximately 500 rounds. With the addition of the patch, the fuzzing process can now be repeated for over 30,000 rounds.

Test: m, fuzzing
Fuzzing: mma mdns_service_fuzzer && adb sync data && adb shell /data/fuzz/arm64/mdns_service_fuzzer/mdns_service_fuzzer
