Add LOG_TAG to HidlLazyUtils

Set LOG_TAG in HidlLazyUtils to make it easier to debug. Previously
HidlLazyUtils inherited log tag of HAL, making it difficult to know if
HAL was using HidlLazyUtils or its own onClients callback.

This matches behavior of AidlLazyServiceRegistrar, which also sets
LOG_TAG.

Bug: 157451814
Test: atest hidl_lazy_test, logcat -s 'HidlLazyUtils:*'
